Per-layout and shared settings

Per screen: the choice that decides which sections the page shows 9:41192.168.1.107

Per layout

The controls whose tips say Set per mode: One, Two, and Four per screen each remember their own choice here. keep three values, one for each layout, and the page shows the one for the layout you have chosen with Per screen:. They are:

The title style (Title Area).
The price-area switches: 24h Vol, Market Cap, Market Cap Rank, 24h%, and the chart helper lines.
The Show … for: time.

One per screen kept on the name-only title style Two per screen kept on its own icon-and-symbol title style

Switching layouts brings back what you set for that layout; nothing is overwritten. The two pictures above show One and Two per screen each carrying its own title choice at the same time, on the same ticker.

Shared by the ticker

Everything else has one value: the coin list and its pause marks, the chart ranges and label position, the colorset with its custom colors and V/M letters (which are kept per colorset rather than per layout), brightness and quiet hours, the address popup rows, and everything in the Device section.
