Prioritize active users in a file by last one I followed

I often follow a person, then wander off to look at something, then want to follow the same person again. Somehow it seems like the person I want to follow is usually in the avatar overflow menu. It would be very helpful to have the avatars sorted by recency so people who I’ve most recently followed can be followed again with one click.

Alternately, promote avatars if other people are following them.
