Ubsericht App to show modes

[davelosert]

Idea

WIth the mode function in #27 , I'd be great if there would some sort of visual to show once the users enter a mode as well as which options of keypresses they have.

Kind of like they do in I3WM.

This could be done with an Ubersicht App.

Unfortunately, Übersicht currently does not support showing widgets on top of windows (see felixhageloh/uebersicht#97). Therefore showing modes or keybindings would only work in a specified status bar - which I am not sure is a good idea as it does not leave lots of room. E.g. a "resize" mode might have 8 - 12 keybindings and I currently can't imagine how this might look good in a status bar.

I researchd a bit about maybe using hammerspoon's canvas instead - but as I have no experience with lua-scripting, this is more work than I anticipated. So this feature might have to wait a bit till I have a new idea, or a contributor implementing this in hammerspoon.
