Settings

Every adjustable option, where it is stored, and who it affects.

Three kinds of setting, three places they live.

Open Settings from the gear in the menu bar (Edit › Preferences, ⌘K / Ctrl+K). The window has a rail of sections; every change applies at once — there is no Save button outside Keyboard Shortcuts.

KindSectionsStoredAffects
PreferencesGeneral, Canvas, On Air, OutputThis browser (localStorage)Every editor window in this browser. Export / Import moves them between machines.
Show settingsShow (and its Format)On the pageEvery editor, /view and the HTTP API. Undoable in the editor, saved with the page.
Machine settingsSystemOn the server (data/machine.json)Every browser using this server. An environment variable that is set still wins.

Every section except the shortcut ones has Restore Defaults… in its header. System also has Reset all preferences…, which puts General, Canvas, On Air and Output back at once — shortcut sets, show settings and machine settings are not touched.
