Settings (Preferences)

EffectCraft ▸ Settings (macOS) or Edit ▸ Preferences (Windows/Linux), Cmd+Alt+;. The dialog has After Effects 2026's pages (General, Startup & Repair, Project, Composition, Previews, Appearance, Grids & Guides, Labels, Type, Import, Export, Audio, Disk, Memory & CPU, Video, 3D, Scripting & Expressions) with OK, Cancel, Previous and Next. Older page names still open the right page (prefs.open {"page": "Auto-Save"} opens Project, Media & Disk Cache opens Disk, Memory & Performance opens Memory & CPU).

The model is effectcraft_engine::prefs::Prefs: serde, versioned (version), addressed by dotted keys (general.undoLevels, autoSave.intervalMinutes, labels.3.name). It is stored as prefs.json through the session's ConfigStore (the desktop app uses the platform config directory: ~/Library/Application Support/EffectCraft on macOS, %APPDATA%\EffectCraft on Windows, $XDG_CONFIG_HOME/effectcraft on Linux; the web app can back the same trait with localStorage). Loading migrates older layouts, keeps unknown keys (from newer versions) and falls back to defaults for values that don't parse.

Commands (CLI, MCP, control channel):

Command Parameters
prefs.get {key?} (omit for everything)
prefs.set {key, value} or {values: {key: value}}
prefs.reset {page?} (omit for everything)
prefs.open {page?} opens the Settings dialog
prefs.pages the page schema: every row, its key, type, range and whether it is wired
