Recently shipped

Delivered in Windows v0.1.1.A:

• ✅ Outline padding — polygon-offset outline around pieces
• ✅ Merge adjacent flaps — union of neighbouring tab polygons
• ✅ Join connected cut edges — reconnect adjacent isolated cut edges

(Bringing these three to macOS is tracked under macOS parity below.)

Windows

Priority	Item	Notes
🟢	Select symmetrical pair	Pick an edge/piece and auto-select its mirror
🟢	Split window	Detachable / side-by-side 3D + 2D panes
🟢	Change coordinates	Re-origin / re-orient the model interactively
🟡	Test coverage	Unit tests for FlapOverride serialization + GlueTabGenerator border modes
🟢	Settings wiring	EditFlapsViewModel hardcodes 5 mm / 45° — fall back to AppSettings
🟢	Corrupt-data warning	FlapOverride.Deserialize silently ignores bad data — surface a warning

macOS

Goal: reach feature parity with Windows, then graduate from alpha → beta.

Priority	Item
🔴	Port the v0.1.1.A layout features (outline padding, merge flaps, join cut edges)
🔴	Verify full feature parity — resolve the ❔ rows
🟡	Extra import formats (Assimp equivalent)
🟡	Notarized, signed distribution (Developer ID)

Cross-cutting

Priority	Item	Notes
🟢	Performance	Overlap detection now uses a spatial grid; profile meshes > 2000 faces for remaining hotspots
🟢	Docs	Fill wiki placeholders (demo GIF, per-step screenshots); add a Glossary — see Glossary
