I'm not quite sure I understand your pattern. Can you explain it more so I can better understand? Maybe I'm missing something and I'm always looking to improve my workflow.

Locally, I don't get the point. I can do tabs and splits. A session? That's another window. I can also hide that and use keyboard shortcuts to navigate towards it. Am I missing a local benefit?

The session is the thing I use, and I do use tmux every day, but I exclusively use it when in ssh as on a local machine I have everything I need. You mention the hybrid, but isn't the point that the connection is ephemeral? We don't exactly want to keep it alive unless we are actively using the connection, right? This is what I'm not understanding about your mixed scenario. What is the difference between what you do and me just opening another pane in ghostty and doing the ssh there. I can't detach from ghostty, but I can save the window state (or move to a different window in a different workspace or just cycle through windows like I would a session) so when I quit it it resumes, but honestly, I rarely quit it. Keeping a remote connection alive while there's no active usage seems like a waste and it's just going to disconnect when I walk away from my machine anyways. So what is the difference?

I do find sessions tend to get unruley easily, and more easily than windows just do to being hidden another level deeper. It's not too bad when single user, but I'd still suggest organizing tabs over multiple sessions, in most cases. That's because it is easy to just leave something like an editor open and accidentally overwrite files. Someone just logs back in after awhile and types :x into vim (or :x!) without thinking. It's also just too easy to let sessions stale. I haven't worked with a single person (myself included) who did not have a tmux session that was inactive for at least a month more than their last login time. (Better than all the hanging VSCode sessions though) That's like people using srun to run slurm jobs instead of submitting a batch job into the queue. That's totally fine to do when you're sitting in front of the sim but if you walk away and the code errors or just ends before your session ends then you're just hogging a machine that could be used (there wasn't even a benefit to this either!). Locally, it's pretty much the same thing except locally I can do all my tabs and splits and sessions without tmux.
