Finally figured out how to read view contents 

I think I'm finally getting the hang of Gocui, it's pretty interesting
how it separates each view into a different section for the layout
function, also went ahead and separated the keybindings into their own
function, and yes I'm stealing from the _examples folder of the official
project, it's really helpful okay?
