Show HN: spymux – Spy on your tmux panes (github.com)

I had motivation for writing this after I kept switching back and forth between agents to see if they've finished what they were working on (and I couldn't find a similar tool out there). I'd imagine it can be useful for other scenarios as well, e.g. tracking multiple build/test jobs over multiple windows.

Still a work in progress, but I thought I'd share :)
