Good point.

What would a sensible approach be for a not-animated activity indicator?

[Jacalz]

Hmm. I don't know actually. Thought about it a bit but a widget designed basically only to indicate time passing is hard to do to without animations. My best guess is that we could just have it be solid some way like how the Entry cursor behaves when not blinking.
