Only cover the widget types that were recently refactored.
A few conventions are set as followed:
* Textwidth is preferably 80, since the whole point of tiling windows
is to be able to view more pane of codes
* Standard, 3rd-party and local require should be grouped together
* Closing parentheses should not be on lines by themselves
There should be a style guide to clarify these.
