Love it! I've been doing this manually when I need to restart my hosts :) Would it be possible to have instructions to install it that don't involve executing a script? Something as simple as the dependencies I need to install and the tmux config required would be super helpful.

Sure! I'll add this tomorrow :P

I forked Zed to pass a ZED_TERMINAL_ID which is tied to the individual shell pane, using it to restore whatever agent session I had running in that pane. I keep 10+ Zed windows open with 1 to 4 agent panes, a reboot used to be a disaster.
