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.
