Maybe I'm in the minority, but I gave up on Zsh/OMZ/Powerline and all of that. I went back to plain bash and keep it simple.

Zsh is cool to look at and has a couple useful plugins, but the whole thing slows down your shell start up and adds a slew of dependencies that may go on life support, or under control of a foreign government.

I'll just stick with bash. It's ugly. It doesn't have pretty auto suggestions but at least it works and it will be there forever.

OMZ is definitely super slow, but there are a few competitors trying to speed start times up, with nice results (50% to 80% reduction).

For style just use starship.rs

I too preferred simplicity, so I just hacked together a basic script of my own to get a similar result.

I am the life support now.
