I guess it's the end-goal then, though. If your goal is to become a rockstar and play the guitar in a band, GH is probably a very bad route to it. But if it is to "have fun" its perfect.

Same with this vim: if you just need an editor that is recognisable and "not weird" then this modeless vim might be useful; though why not just install nano, pico, gedit, notepad++ or even notepad.exe?
