Hey man! Thanks for trying =)
I didn't actually expect you to try, but it's cool that you did. I guess what would need to be done is actually have 7 different skin sets, each with JUST that button changed... but that would be all too much work for no real return. (Can you imagine, in a skin set that you had several options a person might want to change, you'd have to create a different skin set for every possible combination of options!
Still very excited about what you've got so far. I'm tempted to jump into Skinviewer and see what I can do with it myself... maybe I can change that button after all.
I'm surprised though... you've only played for two hours? Can't wait to see what you come up with after playing for a while and have some time to get the creative flowing.
