I've been looking at the webstore and I have a simple suggestion that would streamline skinning a bit.
There's already body class on each webstore page that says something like "webstoreofferdetail", or "webstorecart". The problem is that this is different for every page.
It would help if all of the pages had the same class as well as a more specific class. Something like "webstore offerdetail", and "webstore webstorecart". This would help me to identify specific items on the webstore page without needing to write a huge selector that says ".webstoreofferdetail h2, .webstorecart h2" etc. I could then remove all the extra css and have simply "webstore h2", and it would effect every h2 in the webstore.
Thanks,
