Tool header buttons — Boundaries and Pin Masks controls appear directly in the tool header bar during paint modes, with inline checkboxes for quick toggling.
Addon preferences panel — Configure custom keyboard shortcuts for Toggle Boundaries, Toggle Pin Mask, and Clear Selection. Set startup defaults for all settings (boundary types, pin mask, normal angle).
Startup defaults — Preferred boundary settings are automatically applied when opening a new file.
Changed
Removed D / Shift+D default keybinds — These no longer override user keymaps. Toggle shortcuts can now be assigned in the addon preferences instead.
Mask clearing safety — Timer-deferred clears only toggle use_paint_mask off; full polygon writes are reserved for user-initiated actions when no stroke is active.
