It seems like your major objection is persistence of your session (which is more than just editor instances) but it includes your shells, their position on filesystem, your terminal splits, their position and color etc. There is a tool that handles exactly that and its called tmux. It allows you to create a session (or multiple sessions), create windows, position them exactly the way you like, open your editor of choice in one or more of them, or have other tools display useful information etc. And these session survive restarts, and you can connect to them through ssh etc. And you can navigate those windows with keyboard or mouse etc.

This is useful for long running work, but more often it is not necessary. If you are just exploring the code base or making small edits here and there you don't really need persistent tmux session for that.
