I make a ton of progress with ipython and vim/st3/other text editor with a vertical split. I sometimes screen the terminal in two if I want to run external elements.

We seem to keep iterating back to that modality, but honestly, it's just nice. VS Code starts there but then Java language servers and broken Python language servers and rust language servers and exploding npm dependencies and supply chain attacks just muck everything up.

Simple simple simple is so refreshing.
