This goes into “things you’re allowed to do” (Previously: List of good things - serhii.net) territory, but:

• previously, screen/tmux’s use case was “ssh into a server far away and let things run even when your SSH session disconnects”
• had two terminals open on a remote server, had to edit the exact two files every time, over days and disconnections
• just realized that I can just have a screen session open with vim and the files I edit, and just attach to it next time I’d doing something on that server, whenever that is!
