Can anyone tell me how is this different than tmux?

Mostly it’s the agents view, it’ll show the status of and let you quickly jump to all the agents you have running in any pane/tab.

It also has a default config that’s much easier to use than tmux, letting you use the mouse or simpler (IMO) keyboard shortcuts

Built in worktrees are nice too.

I guess I have to download and try. It does not sound too exciting to me.

It also might just not be much use for you, especially if you’ve been using tmux for a long time and have a set up you like.

Wow. We have gone full circle.
