 Double-click the tray icon to open Settings, the bold default menu item.
+Settings and the snippet editor run on demand in **KSwitcher.Config.exe**, beside the main executable.
+Repeated launches activate the existing configurator; closing its last window exits that process.
+Saving applies changes immediately through the resident KSwitcher process. The configurator does not
+load clipboard history, dictionaries or global input hooks. Clipboard history and the log viewer remain
+in the resident app. Screen capture and all screenshot editors run on demand in
+**KSwitcher.Screenshot.exe**. The capture hotkey starts it; subsequent captures reuse the same
+process. Closing the last editor (or cancelling the only selection) exits that process. It does not
+load resident settings, dictionaries, clipboard history or keyboard hooks. Editor windows have
+stable numbered titles within that process. Keep all three executables together when copying or
+updating the application. Close screenshot editors before installing an update.
+If settings change in the tray while the configurator is open, a conflicting Save is rejected; reopen
+the configurator to load the latest settings.
+Updates from v0.3.x–v0.4.1 first install the compatible **v0.4.2 bridge** through
+Update in the tray menu. Select Update again to install the full current release;
+manual extraction is not required. Future full releases use stable `release-vX.Y.Z`
+tags, which the bridge and newer clients recognize. Older clients ignore those tags
+and continue to find the bridge instead of skipping it. Versions v0.2.3 and earlier
+still require the previously documented initial configurator migration.

+Modern ZIPs contain `release-files.json` (schema, version, file paths, sizes and SHA-256

+### Screen capture and annotations
+
+Press **Win+Shift+S**, choose **Capture screen region…** in the tray menu, or run
+`KSwitcher.exe --capture`. Drag a rectangle on the dimmed, frozen desktop; the selected area stays
+at normal brightness. Escape cancels. Selection and annotation frames are buffered to avoid flicker.
+The selected area is copied immediately, the fullscreen selection is hidden, and a Windows notification
+is sent. Click the notification to open the editor. Enable **Open editor after screen capture** in settings
+to open it automatically; this option is off by default. An immediate notification error still opens the editor.
+Existing saved preferences are preserved. Windows Do Not Disturb can send notifications directly to the
+notification center without showing a banner.
+The preference applies to each new capture, including while other editors are open.
+KSwitcher also sends a notification with a thumbnail. Notification identity and activation are registered
+at resident startup and refreshed before sending; registration/submission errors are written to the log.
+Click the notification to reopen the original screenshot, including after the screenshot process has exited.
+Originals in the local notification cache are DPAPI-encrypted. Thumbnail PNGs live in a separate
+per-user cache under ProgramData, readable only by that user and SYSTEM, so the Windows notification
+broker can load them even when the profile directory is inaccessible to it.
+Notifications expire after 24 hours. Cache cleanup runs on capture/open; each cache is bounded to
+40 files and 256 MiB. Expired or evicted notifications cannot reopen their screenshot.
+In the editor, **Ctrl+C** or **Enter** copies the current result without closing the window.
+The editor starts with **Pencil / Freehand (F)** for drawing. Choose **Pointer (V)** to select objects, move them, and edit geometry, thickness and
+other properties using handles and controls. Clicking empty space clears selection; dragging empty
+space adds nothing. Choose a drawing tool to create objects, then return to **V** to edit them.
+The cursor identifies the active tool: pointer, text caret, pencil, or a crosshair with the drawing
+tool symbol. Move/resize/thickness/rotation handles override it with their action cursor. Custom
+cursors scale with display DPI and use a contrasting outline for light and dark images.
+To annotate: **N** places sequential numbered red markers with a click, and **A** draws
+red arrows by dragging from the tail to the tip. With **Pointer (V)**, click an existing marker or arrow to select it;
+drag its body to move it. Drag the square handle on a number's right edge to change its diameter
+(the text scales with it), or either endpoint handle of an arrow to change its length and direction.
+Select an arrow and drag the extra handle beside its midpoint perpendicular to the line to change
+its thickness from 1 to 30 pixels. The arrowhead scales with the line. Minus/plus keys also work.
+Alternatively, scroll the mouse wheel over an arrow to change its thickness, or over a number to
+change its diameter. Wheel up increases the size; wheel down decreases it. These edits support Undo
+and update linked arrows. **Ctrl+D** clones the selected object with a small offset. A cloned number
+gets the smallest available positive number, just like a newly placed number: gaps left by deletion
+are filled first, without renumbering existing objects. A cloned arrow keeps its style but starts without endpoint links.
+Arrow and line endpoints can attach to numbered markers, rectangles, circles, ellipses, text blocks,
+and other arrows or strokes. In Arrow or Straight line mode, hold **Ctrl** and drag from one object
+to another to draw over them and automatically attach both endpoints. Without Ctrl, existing objects
+can still be selected and edited as before. With Pointer, drag an existing endpoint onto a target to attach it. Attached endpoints follow movement and resizing; text attachments
+also follow rotation. Arrow-to-arrow attachments retain their relative position along the target line.
+Clicking a connector or adding/editing its caption preserves its links. Moving the whole connector
+intentionally detaches its endpoints; moving one endpoint detaches only that end. Deleting a target
+leaves connected endpoints at their last position. Self-links and circular dependency chains are rejected.
+The compact toolbar uses [Lucide](https://lucide.dev) icons with hover tooltips showing each action
+and its keyboard shortcut.
+Drop either arrow endpoint onto a number to link it to the circle's edge. Linked endpoints follow
+the number when it moves or changes diameter. Drag an endpoint away to unlink it; moving the whole
+arrow unlinks both ends. In Arrow mode, hold **Ctrl** while dragging to start a new arrow directly
+from a number. Deleting a number leaves its arrows in place and removes their links; Undo restores them.
+**Delete** removes the selected object. **Ctrl+Z** (Undo) reverses additions, moves, resizes and deletions
+(up to 100 actions). **Ctrl+Y** or **Ctrl+Shift+Z** (Redo) restores undone edits; a new edit clears the
+redo history. Undo and Redo buttons are disabled when unavailable. Enabled toolbar buttons use a
+hand cursor. Selection handles are visible only in the editor, never in the copied image.
+The **palette** changes the selected object's color: arrow, numbered marker, or highlight.
+It also sets the color for newly drawn objects of every type. With nothing selected, only the
+color for new objects changes. Number text switches between dark and white for readability.
+**Highlight (H)** paints a translucent freehand marker stroke. Dark text remains readable beneath
+the highlight. Drag a selected stroke
+to move it, scroll over it to change width (4–100 pixels), or use Delete / Ctrl+D / Undo / Redo.
+Hold Ctrl while drawing to paint a new stroke over an existing object. Highlights render beneath
+arrows and numbered markers. The palette's color indicator reflects the selected object, or the
+color for new objects when nothing is selected.
+The editor status bar shows contextual tool, selection, rotation and text-editing hints.
+Hover a toolbar button to see its action and shortcut; the title stays **KSwitcher — Screenshot**.
+**Text (T)** adds text directly on the image. Enter inserts a line break; Ctrl+Enter or a click
+outside commits the edit, and Escape cancels it. Double-click text or press F2 to edit it again.
+The **Aa** icon opens the standard font dialog for family, size (6–200 pt), bold and italic.
+The mouse wheel over text adjusts its font size. Text supports color, dragging, Ctrl+D,
+Delete and Undo/Redo. Arrow keys move the selected object by one source-image pixel;
+selecting an arrow caption moves only that caption. Repositioning a caption preserves its
+automatic angle; only dragging the rotation handle switches to a fixed angle.
+New standalone text starts horizontally, even after editing an angled arrow caption. Font styling
+is reused; rotation belongs to each individual object.
+Text has a rotation handle above its selection. Drag to rotate; hold Shift to snap to 15-degree steps.
+Double-click an arrow, press F2, or use the label icon to add/edit its caption. Captions follow
+the arrow when moved or resized; drag the caption to adjust its offset. By default, the caption
+angle follows the line (or middle curve segment) and stays upright. Rotating its handle manually
+fixes its angle; Shift snaps to 15-degree steps. Undo restores automatic mode. The Aa icon changes
+the selected caption font, and the mouse wheel over it changes its size. Captions and rotation
+are included in clipboard export, cloning and Undo/Redo.
+**Straight line (L)** creates a line without arrowheads. **Rectangle (R)**, **Circle (O)** and
+**Ellipse (E)** create transparent shapes with colored outlines. Drag the two corner handles to
+resize; circles keep equal width and height. Move shapes by their outlines, adjust thickness with
+the mouse wheel or side handle, recolor, clone with Ctrl+D, and undo/redo as with other objects.
+Hold Ctrl to start drawing over an existing object. Line style applies to outlines; Ends is disabled
+for shapes.
+**Freehand line (F)** draws an opaque curve by following the mouse. The curve is one object:
+move it, change its color or thickness, clone it, or drag its endpoints. Hold Ctrl to start a new
+stroke over an existing object. The **Line style** selector supports Solid, Dotted, Dashed and
+Dash-dot; **Ends** supports an arrow at the end, start, both ends, or no arrows. These settings
+apply to selected straight/freehand lines and set defaults for subsequent lines. Both are disabled
+for numbered markers and highlights unless a line drawing tool is active. Undo/Redo includes style changes.
+The window close button asks for confirmation before discarding an uncopied screenshot.
+**Escape** cancels region selection or inline text edits; it does not close the editor. Copy keeps the editor open and publishes the image
+at its original pixel size, ready to paste. The preview fits the window without changing export size.
+The shortcut is configurable in Settings under **Screen capture**.
+Each capture opens an independent editor available through Alt+Tab; use the shortcut again to take another screenshot while
+keeping earlier editors and their annotations open.
+Captures use ordinary clipboard history settings and limits. Protected video and secure desktops cannot be captured.

 # Latest Windows release

-## v0.2.2 — 2026-10-28
+## v0.6.11 — 2026-10-29

- Fix the garbled dash in the executable description shown by Task Manager and Windows file properties.
- Explicitly compile the UTF-8 Windows resource source as UTF-8, both in the resource file and the portable build command.
- Add regression checks against the compiled executable's version and exact Unicode description.
+## Changes
+- Show an update progress window for manual checks and installation. Downloads display percentage and received/total size; verification, unpacking, installation and restart have distinct status messages.
+- Keep the progress window running independently while KSwitcher exits and restarts. After the new application confirms startup, show the installed version and a Done button in the same window, without a separate completion notification.
+- Show recovery and installation errors in the same window after the application exits. Background update checks remain quiet.

-Verified: 168 native checks, 51 input/layout checks, and 26 updater/metadata checks.
-The executable description is `KSwitcher — native keyboard and clipboard utility`.
+The progress UI is provided by the currently installed updater. Updating from v0.6.10 to this release still uses the older interface; subsequent updates use the new window.

-Download **KSwitcher-win-x64.zip**, extract the entire archive to a writable folder,
-and launch `KSwitcher.exe`. Keep `dictionaries/` next to the executable.
-The archive contains the application, offline dictionaries, documentation and license notices.
-It does not contain personal settings or clipboard history.
-`SHA256SUMS.txt` contains the archive checksum.
+## Validation
+214 native regression checks, 466 input/UI checks, screenshot editor UI checks, isolated notification registration, 45 updater regression checks, and progress-window checks for download, installation, recovery and completion states. Network tests verify real download progress and release download/checksum validation. Startup acknowledgement tests prevent reporting success for ordinary startup or a missing updater handshake.

-From version 0.2.1 onward, use **Update** in the tray for future releases. Startup checks notify;
-installation starts only after confirming Update. Older versions need this one manual upgrade:
-exit KSwitcher and replace the application files, retaining `data/` and any customized dictionaries.
+**Upgrade:** choose Update in the tray menu. Legacy v0.3.0–v0.4.1 clients first receive the v0.4.2 compatibility bridge, then the current full release. v0.2.3 and earlier require manual installation.
+For manual installation, exit KSwitcher and extract the entire ZIP into its installation folder. Keep personal `data/` and customized dictionaries.

-This folder holds the latest compiled version; older versions remain in Git history and Releases.
-To refresh the tracked package from source:
+Download **KSwitcher-win-x64.zip** with **SHA256SUMS.txt**. The package contains all three executables, a release manifest, offline dictionaries, documentation and license notices. It contains no personal settings, clipboard history, Tesseract installation or language models.
