Typically I use vim+tmux, so I should have also probably set up some additional extension to add a tmux-like panel change shortcut, so I could save-and-run like I normally would on the command line.

It also didn’t seem to handle Jupyter cells well. I forget exactly, but sometimes it would jump from one panel to another instead I think?

There is always something once in a while that steals the focus from the text and forces you to click back.
