Yep the UV tools, even though they have been greatly improved in the latest version, are still pretty basic compared to ones i’ve used in other packages.
There is a page on the autodesk website (maybe maya website) where people are voting what features they want to be included and I know one of them is for support for plugins such as ART and a couple of other i think aimed towards game creation. There was another forum on here with a link to it asking for everyone to vote that one up in particular. You could probably find it by searching the forum, I don’t think it was too long ago.
