Oh wow :) thank you for cmux, it's a great project!

The code is here: https://code.pecheny.me/pecheny/cmux or if you prefer github, https://github.com/alexander-pecheny/cmux

I think I only added two features, pasting images over mosh (ssh already worked but not mosh) and a compact version of sidebar.

The story behind the fork is: I had a bug with raycast, filed a PR that fixed it for me https://github.com/manaflow-ai/cmux/pull/2435, a different fix made it into next release that for me didn't work. Maybe the problem was on my side, but at this point it was easier to fork the working version than debug further.
