My interactive shell experience has substantially improved after installing Starship. :) The other thing was changing from Bash to Fish.
Trying to get it working on WSL (Ubuntu 20.04 and Centos) as well as MSYS just wasn't happening. On the few occasions I did get it working, it was unbearably slow. Simple commands would have sometimes half a second of delay. I could time what was causing the slowdown and disable some of it, but by the time I got it bearable I had disabled basically all of Starship. Then there were font-related issues on top. Ugh.
I hope others have a better experience than I.
