v4.0.4

Added

• Customizable toolbar background color — new "Background color" setting in Preferences > Appearance. All toolbar text, icons, borders, and system controls adapt to stay readable on any background.
• Adaptive toolbar appearance — toolbar and popovers automatically switch between light and dark AppKit appearance based on background brightness.
• Export dimensions dropdown — scale down recordings before saving (Original, 75%, 50%, 33%, 25%). Applied at export time; recordings always capture at full resolution.
• Estimated export file size — shows estimated output size in the video editor when trim, scale, or format change would affect the result.

Fixed

• Multi-line text clipped after commit — text snapshot now uses the same measurement as the rendering engine, preventing the last line from being cut off at non-default font sizes.
• Ctrl+lasso broken in pencil mode — Ctrl now enables instant annotation selection in pencil mode (no long-press delay). Multi-selections can be dragged without holding Ctrl, matching all other tools.
• Pen pressure over-smoothing after many strokes — committed annotations are now drawn from a cached bitmap during active drawing, preventing progressive frame time degradation that caused macOS to coalesce tablet events and reduce stroke fidelity.
• Pen pressure range — light touch now gives 20–100% of stroke width (was 30–100%) for finer control.
• Apple Translation language list empty on first use — the Translation framework can return stale results at launch; empty results are no longer cached, so the language picker retries on next open.
• Global hotkeys stop working after closing editor — NSApp.hide(nil) could suspend the Carbon event loop; replaced with cooperative focus transfer.
• Window snap highlight not showing on overlay appear — snap query now runs immediately at the mouse position instead of waiting for mouse movement. (PR #100, thanks @TimFang4162)
• Smoother refined pencil stroke tails — end of refined strokes no longer has an abrupt straight segment.
• Cursor flicker after finishing a stroke — the annotation cache is now incrementally updated on commit instead of rebuilt from scratch.
• Video editor bottom bar overlap — left-side info gracefully hides when the window is narrow instead of overlapping action buttons.
• Timeline thumbnail seams — sub-pixel gaps between thumbnail tiles eliminated.

Changed

• Lasso selection moved to Ctrl+drag — frees Shift for line/shape constraining without timing conflicts.
• Video editor minimum width increased to 820px to ensure all controls fit.
