UI Mods: Pros & Cons

[mdfreak76]

Hey all! Here are some questions i pose to anyone who could help me out in choosing a user interface, and maybe get some ideas for developers...

Do you currently use any UI mods?
If so what do you use?
Is there anything in particular that keeps you using it?
Have you tried others?
Is there a reason you don't use (the others) anymore?
If you could change the program you are currently using in any way, what would it be?
Is there anything i forgot to ask?

I know they are n00b questions but I am a n00b, and everyone has to start somewhere. I am trying to answer my own questions by going thru the interfaces here, but it would be silly for me to reinvent the wheel when everyone here is obviously here for a reason and probably has at least one opinion they can share with me... Thanks everyone... see you in Queynos...
