Just tried it out and it's cool, but zsh doesn't play well with most ttys when you mess with the prompts like that.

Did lead me down a rabbit hole to oh-my-bash though which is pretty nice and runs on regular bash. Even has a powerbash10k theme lol.

Also found ble.sh which adds syntax highlighting and fish/zsh style atocomplete to a bash shell (written in pure bash). It's slow as turds so I just aliased it to make it easy to enable/disable.

Looks like I'm sticking to bash lol
