I'm currently using LunarVim, which is poorly documented, painful to install, update and configure, and with lots of tiny issues that I've spent hours trying to fix. But, it's still the best thing out there!
I would pay a ton of money to whoever can solve this problem.
Another thing I would pay money for is a terminal based python REPL that resembles a jupyter notebook. The IPython repl doesn't cut it for me and is missing a bunch of features, and projects like Euporie are missing things that I like in IPython. So something that borrows the best of both worlds would be incredible.
