Feature: Add shortcuts in the GUI

[Obscurely]

I've tried adding shortcuts, but the problem was on evey window change you would have to again click on it and didn't really find a solution for it. The problem probably is with the way I structured the GUI or maybe I wasn't doint it right.

The goal is to be able to open the Falion GUI after which you should be able to fully use it with only the keyboard and same keybinds as the CLI.
