v0.2.3

Selection & marquee

• Adjustments now clip to the active selection
• Marquee square/from-center constraints when no selection exists; selection-tool modifiers reworked — Alt = expand from center, Ctrl = temporary Move
• Move/marquee snapping disabled when zoomed in, for pixel precision
• Fixed transform-commit dropping a moved selection's content

Tools

• Dodge and Burn split into separate flyout tools
• Move tool: 1 px alignment when zoomed + arrow-key nudge
• Merge Down / Merge Layers now merge only visible layers
• Real OS bitmap cursors (eyedropper) and the arrow hidden under brush/rotate rings, plus eyedropper image/cursor polish
• Tool tooltips show the quick-pick shortcut key

View & navigation

• Scrollbar thumb reaches the true end (grab anchor); pan offset clamped so a scrollbar drag can't strand the view
• Opened transparent images become normal layers, not backgrounds

Appearance

• Toolbar icons inverted for dark mode instead of flat-tinted, plus icon upgrades
