Settings: 56 of 59 not-yet-wired settings now change behaviour (nested-comp switches, constant vertex count, related-item time sync, match-name pick whip, split-layer order, Home on open, motion path span, internal wireframes, zoom quality, label-coloured tabs, mask colour cycling, gradients, grid/guide styles, text engine, font preview/recent/native names, missing frames, unlabeled alpha, drag import, default output folder, segmenting, bit depth names, preview sample rate, disk/media/conformed-audio caches, RAM reserve and low-memory reduction, Video Preview window, 3D reference axes/extended viewer/draft shadows, script file gate + File.execute warning, expression editor options and error banner). Three stay display-only and are documented. Features: Convert Audio to Keyframes, RPF Camera Import (JSON/CSV camera data), keyframe colour labels + Select Keyframe Label Group, Recent Animation Presets. Menus: Edit > History, File > Import Recent Footage, Replace Footage > With Layered Comp, Save a Copy As XML (.ecprojx, opens again), Composition > VR (Create VR Environment, Extract Cubemap), Assign Shortcut to 3D view / workspace, Window viewer labels + open viewers, Help > System Compatibility Report / Enable Logging / Reveal Logging File. Dynamic menu nodes (@dynamic:…) shared by the egui and native menus. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
