Instead of a stack of terminal tabs you have a building. Each project is a floor; each session on it is a worker with a callsign (HOLMES-42) it keeps for good, across resumes. You see at a glance who is working, who is done and who is waiting on you, and you go to them in order.

Local only: no accounts, no external services. macOS, or Windows through WSL 2.
