I went down this path over 6 months ago and had a variety of custom setups using tmux, cmux, and more. But since using Orca IDE it feels like a leap in usability and robustness.
I found orca way to cluttered and overkill.
Cmux feels very lightweight.
I love CMUX and some people I know who were building their own tmux setups bailed and just started using CMUX -- The built in browser and associated bash tools are awesome but really just having workspaces with colors and todos that survive a refresh makes it worth it if you run a bunch of agents at one time
