Our team's `git branch` output is a graveyard. Sorting by last commit would be a godsend for quickly identifying active work and stale branches.

When I'm working on a repository where the remote is shared (like a corporate GitHub repository where not everyone has their own GitHub fork) I tend to name all my branches like 'eru/<something>'. That way I can quickly find my work, and I can also confidently delete branches without worrying about stepping on other people's toes nor being stepped on by accident. I encourage co-workers to do the same, but haven't strictly required it from team members.
