Element ID's

[sorkvir]

Hello all,

I've been lurking in these forums for the past couple of days absorbing as much as a I could while I work away on a UI. I have ran into a few things and I can't seem to find an answer.

First off, I'm assuming that only the items listed here can be skinned, correct?

Additionally, where can I find element ID's? I've seen some pretty amazing UI's from the author's here that utilize these, but I cannot seem to find any documentation on them. If there isn't a list, how can I go and determine the Element ID?

Lastly, any tricks or "gotcha's" the experienced authors would mind sharing?

Thanks everyone!
