You can organize terminal sessions as collapsible trees and then branch from any shell, rename sessions and keep long-running commands/agents grouped by task.
I built rapunzel because in the MacOS terminal, I had many agents running across tabs but they were difficult to track. I built it because I love the Tree Style Tab Extension in Firefox. I built it because, it is the time for Chrome, but for agents. I made it, to make it as simple as possible and nothing more.
