- Zia Settings, in the ⋯ menu: Zia's settings on a page of their own, in
the welcome tour's glass over the dimmed window, rather than only as Sine's
long list. Its sections down the side, a search across every setting, and
switches, menus and fields; a setting that belongs to another shows only with
it, as in Sine, and API keys are hidden as they're typed. Esc, the ✕ or a
click outside closes it. Sine's list is still there, and both show the same
settings (thanks Bxthesda).
