I'm sorry but I am still confused. What specifically does herdr give me over tmux? "It is designed for agents" is just marketing speech, it means nothing. Ok, it has mouse support, fine, I don't care about that one but I can see how it's useful to some people. That has nothing to do with agents though. zellij also has a better user experience than tmux, so you could just use that or any of the other dozen multiplexers.
I understand it has the agent pane on the left that tells you what is running but... that's it?
