Quite honestly, changing things around isn't as daunting as one thinks it would be with the current system. Especially simplistic things such as changing specific colors. You're welcome to ask what box X is called in the color scheme and I'm sure someone will reply. Also, please take a look
here the link contains both an offline and online template generator with the ability how everything you change will look. Also somewhere around here is a link to image that names all of the table colors in a graphic. As far as any other appearance, if you can't figure it out yourself, ask on this board. I've always found people here are VERY helpful.
Also, my personal opinion, you'd be making a big sacrifice for a bit more complete template system if going to another board. I've seen them all, and this one crushes them. But, is up to you. I've no idea on the skinning features of the other boards, though.
