I don't really get it either. I installed it to try it out, but I still don't understand why it's getting so much attention. I don't even use tmux. My window manager already gives me workspaces, splits, and tiling, so I don't need those features there. I also prefer focusing on a single project instead of juggling five at once. And I don't really care about notifications. I just switch back to the relevant workspace and check on things when I want to. So apart from the agent sidebar, I'm not seeing what problem it solves for me either.
