settings

The system's one control panel: twenty-one keys that every other app can read. Three are switches - darkmode, sound and haptics. Eleven are pickers, from the accent color (fifteen palette names) to the font (mono, sans, serif, display or mrly) and the oscillator wave (sine, triangle, square or sawtooth). The remaining seven are numbers with hard ranges, like scale from 3 to 6 and width from 500 to 1500.

Dials

• launchpad switches the home screen between grid and list.
• render picks cpu or gpu drawing; material picks solid or glass.
• wallpaper is a flat color or a generated pattern, shaped by seed (0 to 999) and detail (32 to 160).
• A value outside its range or off its list is refused, and the old value stands.
• Every change is shared with all apps at once.
