Yeah, this is how I do it. If it's a reasonably modern remote image you even get color highlighting. And in a way, it lets me segregate, "on this host, I'm working on this project, on this host I'm on this project, all the state/context is there when I re-activate my tmux ready to see what's up.

If I'm writing a lot of code or doing a refactor needing more thought, I'll do it locally, to be sure.
