What's new in v0.3.1

Slider control rewrite

Complete overhaul of the slider UI component:

• Drag interaction moved from track bar to label (more intuitive, Blender-style)
• Defaults to unbounded range — no more artificial min/max clamping
• Arrow keys (Up/Down/Left/Right) for fine adjustments, Shift for 10× steps, Cmd/Ctrl for 0.1× precision
• Scroll wheel support on the label area
• Cleaner, more compact design

ESC key fix

Fixed a long-standing annoyance where pressing Escape during a mid-action (drawing a wall, placing a slab, etc.) would both cancel the current action and switch back to select mode. Now:

• First ESC cancels the in-progress action (e.g., clears the wall draft)
• Second ESC switches back to select mode

Affected tools: Wall, Slab, Ceiling, Roof.

STL and OBJ export

New export formats alongside the existing GLB export. Uses Three.js built-in exporters, no new dependencies.

• STL — standard for 3D printing (physical scale models)
• OBJ — widely used in rendering pipelines

Three format-specific buttons in the settings panel replace the single export button.

State management fixes

• Fixed recursive deleteNodesAction that could cause state inconsistencies — now collects all descendants first, deletes in a single batch
• Fixed memory leak in temporal tracking (prevNodesSnapshot persisted across store re-creations)
• Fixed requestAnimationFrame in updateNodesAction without cleanup — could queue duplicate callbacks
• Removed unused debug variable in wall system

Other improvements

• Ghost wall fix — WALL_MIN_LENGTH increased to match grid snap step (0.5m), preventing zero-length wall artifacts that crashed on reload
• Antialias — re-enabled default antialias on WebGPU renderer
• Post-processing — cleaned up pipeline code, improved error handling
• Window panel — removed artificial slider bounds on position, dimension, and frame controls
• Resize handling — added 100ms debounce for smoother viewport resizing
• Community setup — added issue/PR templates, CONTRIBUTING.md, simplified SETUP.md
