Looks good!

Side note - I've noticed the FAB in dark theme has a different content color, not matching the filter button. Not related so I think this would be best in a separate Linear issue?

I noticed that too but wasn’t sure whether to update it. However, since the background is different now and all other purple buttons use white text, I think you’re right, I’ve updated it in this PR.
