00:32.880 Can it replace ssh+tmux for persistent sessions on remote hosts?
01:16.880 I see integration with projectile in the readme. Does it also integrate with project.el?
03:51.240 Can you detach a session from shell-mode and reattach from eshell/vterm/term-mode? Or start a compile in shell-mode and attach it from compilation-mode?
05:45.120 How do you talk to detached? Could it be feasible to run a child Emacs instead of detached?
07:45.880 How does it handle processes that require user input?
09:20.000 Can you rerun a command (session?) but in another directory?
12:22.880 What are some other places where this might be useful?
16:59.720 What are you currently excited about in Emacs?
19:27.400 Bug in detached re: eshell and quotes
