Every version, in the open

Added

Collision Groups

• Per-layer Collision Groups (1-8): layers in the same group pass through each other but still collide with everything else.
• Visual group badges in the layer list and colored group outlines in the preview canvas.
• Select Group action: with one layer selected, instantly select every other layer in its group.

Hitbox System

• Hitbox Type override per layer: Exact Shape, Auto-Circle or Auto-Rectangle for faster, smoother collisions on simple objects.
• Hitbox Padding to expand or shrink collision bounds independently of the visual shape, applied through Matter's body scaling so mass and inertia stay correct.
• Automatic stroke detection pre-fills padding so stroked shapes collide at their visible edge.
• Corner Rounding (chamfer) per layer with real-time feedback while dragging.

Constraints & Chains

• Create Chain: link 2+ layers into a rope or necklace with configurable stiffness, damping and link length.
• Connect Rigid and Connect Spring actions to link selected layers pair by pair.
• Max Stretch limit on spring, distance and chain constraints to stop bodies flying apart under high forces.
• Draggable pin anchors rendered as AE-style crosshairs; drag to re-attach a pin to an exact spot on a body.

Kinematic Timing

• Three timing modes for kinematic layers: Original AE Timing, Start Immediately, and On Collision (holds until hit, then plays its keyframes).

Text Layer Workflow

• Automatic text detection on import, with a dialog to convert to a shape layer, split into one layer per character, or skip.
• Split Shape Layers: turn a multi-path shape layer into one layer per path.

Workflow & Import

• 2x2 import grid: Reload Selected, Reload All, Update Layers (re-fetch geometry while keeping settings) and Add Selected.
• Collision markers on bake: a timeline marker at every frame two bodies collide, for syncing sound effects.
• Sync button to pull the active comp's duration into the duration field.
• Copy / Paste Settings between layers, and Randomize Weights for multi-selections.
• Layers hidden in AE import in Inactive mode automatically.

Interface

• Contextual action toolbar that adapts to the current selection.
• World Presets: Default, Bouncy Castle, Slippery Ice, Moon Gravity, Heavy Sludge.
• Reset to Default button and double-click-to-reset on every slider.
• Static Friction and Sleep Threshold sliders.
• Info tooltips across the entire interface, and an indeterminate progress bar during bake.
