Settings and display
Settings has two groups: a Model group (Connection, Model library, Voice) and an App group (Display, Benchmarks). Nothing needs saving. Changes apply as you make them.
Display and reading comfort
The Display pane controls how the app and story text are laid out. You can set the interface width (or stretch to the full window), scale the whole interface, scale the story text on its own, and justify the prose so both margins are flush, like a printed book.
Shortcuts and the command palette
Ctrl/Cmd+K opens a command palette. From it you can jump to a story, open Community, Templates, or Settings, or start a new story from any template. Ctrl/Cmd+/ lists the keyboard shortcuts, including search within a story (Ctrl/Cmd+F), quicksave (Ctrl/Cmd+S), and loading the most recent save (Ctrl/Cmd+L).
