MercuryWM

Very easy to customize, out of the box. The only thing is that sometimes the terminal does only a single letter. To fix that, just press enter 1-2 times, which would fix it. I definetly recommend at least trying this out if you're into this kind of stuff. (but not if you are inexperienced with terminals.) To customize the terminal, use the commands from the github, which is linked below. https://github.com/wheel-org/mercurywm/wiki/Commands-List
