I would like to see some documentation on what styles for each widget are possible with the engine without having to browse through all the themes on this website and gnome-looks.org . It would be nice to know which features will be used in upcoming versions and what features will be deprecated. For example, give a small wiki page on scrollbars and list of the options with a small screenshot for each style. I don't think any other gtk engine has good styling instructions for themers. I think Murrine already has an advantage with this website, but styling docs would be super helpful.

First, I also posted this at launchpad, but so far mine is the only question there. If this is the wrong place to post a question -- if it should be a bug request or somplace else, please just let me know and we'll nix this post.
