When sorting the topics list by ‘Activity’, there’s not enough space for the arrow, pushing it down below the word. This doesn’t happen for the other options.
It also happens with Views for me - in portrait mode. There’s only so much room. I’m not so sure shifting everything to the left or leaving room for it on the right in the event it displays would be much better.
Got a mock-up of how you think it could be improved on narrower view-port widths?
Or maybe only deal with when there is more room for it?
I didn’t even consider mobile devices - only tested on desktop, sorry. It’s hardly an urgent issue, I just reported it here for completeness.
