Cool project, I like the idea of having tmux-compatible CLI. I used Zellij to get better UX, but many agent tools integrate with tmux. This way agent tools can still integrate tmux as a defacto standard for programmatic interface while having better interface for users.

But I wonder if tmux/rmux design is suboptimal since it couples session persistence and window management together. Do you have an opinion the design which separates the responsibilities? An example that pioneered this approach is abduco, and libghostty-based zmx being a modern implementation.

I thought I was too zealous because I created 11 crates respecting single responsibility principles.. I would have been all in to risk it further and separating responsibilities for session and window management but it would have diverged too much from tmux. I wanted a 1-1 port for now
