+**Smoothing (0–100%)** on the screenshot toolbar adjusts pencil paths. With a pencil
+stroke selected it affects that stroke; otherwise it sets the default for new strokes
+(initially 25%). **Apply to all strokes** applies the displayed amount to all pencil
+strokes in the current image and sets the default for new ones. Shapes, text and
+highlights are unchanged. Zero restores the original path; higher values reduce more
+jitter. The original samples are retained through moving, endpoint editing and cloning,
+so lowering the amount does not accumulate distortion. Each slider drag or bulk change
+is one undo step, and PNG export uses the displayed geometry. Very short strokes remain
+unchanged. Shift-constrained and linked strokes start without automatic smoothing;
+you can explicitly adjust them afterwards. Shape/straight-line recognition is separate
+and does not turn recognized shapes back into pencil strokes.

 **Trapezoid (B)** on the toolbar creates a trapezoid with parallel bases. Pencil recognition also
 fits nearly parallel, unequal bases into a clean trapezoid. Trapezoids support bounding-box resizing,
 rotation, styling and undo/redo; Ctrl+Z after recognition restores the original pencil stroke.
