So today, when I get off work, I'm gonna go home and just start messin around with creating homescreens. I know it's just a short xml file and a jpg so ... can't be that hard, right? ;)
So ... what I'd like to know is what little tricks you guys have learned or what advice you have for a new kid with basic knowledge of coding. I'm just gonna check out the xml files from the ones i already have installed and i should be able to pick up most of it from that but your advice would be greatly appreciated. Maybe this can become a reference guide for people who wanna learn.

Or ... is there already one of those and I'm just being that annoying new kid who doesn't search for things first?
