-- Log failed conversions and suspicious repeated hotkeys with recent attempt context.
-- Include bounded text and layout diagnostics to help reproduce conversion failures.
-- Add the **Write log** setting and preserve the previous log during rotation.
-- View current and previous logs inside the app with Time, Attempt, Event, and Details columns.
-- Copy selected rows and clear the selected log from the viewer.
-- Fix the log viewer closing on focus; give column headers a distinct background.
+- Accept keyboard and mouse input forwarded by Microsoft Mouse Without Borders, including hotkey
+  releases, repeated presses, recent-word conversion and snippets. Mark KSwitcher's own generated
+  input to prevent recursive commands and preserve text-operation validation.
+- Add **Update** to the tray menu and a non-installing startup check against this repository's
+  Releases. Verify the x64 ZIP, SHA-256, executable identity and version before closing; restart
+  automatically and roll back on replacement/startup failure. Keep settings, history and existing dictionaries.
+- Fix initial window sizing on high-DPI monitors. Size the frame and controls from the same monitor
+  DPI, recover windows after display changes, and provide resizing, scrolling and focus visibility
+  when the available work area is smaller than the contents.
 
-Repeated hotkeys are diagnostic clues, not proof of failure. Successful paste dispatch does not
-verify that the target editor applied the replacement. Text diagnostics are enabled by default
-and can be disabled with **Write log**.
+Verified: 168 native checks, 51 input/layout checks (including hidden Settings at 240 DPI),
+24 offline updater checks, live release download/checksum/package validation, and visible Settings
+at 250% scaling. Two-laptop Mouse Without Borders use and physically disconnecting a monitor still
+require hardware verification.
 
 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.
 
-For upgrades, exit KSwitcher first. Back up any edited dictionaries before replacing files.
-Keep your existing `data/` directory to retain settings and clipboard history.
-`SHA256SUMS.txt` contains the checksum of the archive.
+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.
