Display settings redesign
This is a replacement issue for #534 (closed), originally reported in May 2019. The goals remain largely the same, but the designs have developed a bit since then.
Issues with the current display settings panel:
- The top section is really complicated - there are lots of different sections, and it's hard to know how they relate to one another
- Visually it's unbalanced, with the mode button and the arrangement widget competing for attention
- We have these linked buttons which are behaving like tabs, for switching between the settings for individual displays, but it's not really clear what they are, and that's not a design pattern we use elsewhere
- Night light is stuck out on a limb
The latest designs are mostly a refinement of the existing display settings, and aim to resolve these issues.
