Auto-rotation icon unclear
The button which controls automatic display orientation is a circular arrow. The meaning is hard to decode.
Usually this kind of icon is dedicated to verbs like restart, redo, reload, retry. Moreover, clicking it does not cause anything to happen, making it not possible to understand the purpose without an external source of knowledge.
Here are some concepts that might be useful for creating a better icon:
- that display orientation has only 4 cardinal directions
- that display has just 2 shapes: portrait and landscape
The clearest icon I can immediately think of is something presenting the 2 possible display shapes, and an arrow connecting them.
