So I'm re-doing all my cabling. I didn't like the messiness with the cables that came with my buttons, I'm a bit OCD like that.
Here's what I have for my regular switches -

Mostly pay attention to the yellow/blue buttons setup.
As far as the grounding goes, can I do something similar and just have a single ground cable come from one side of the board, and a single ground come from the other side, join them up and put them into the single ground connector? Or do I have to have one single cable hop between 32 different ground connections?
I can attempt to explain better if needed.
