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.
