A single login for all features would be nice. It is weird seeing multiple logins on a page for different sub-sites. Newbies (and people who visit infrequently who haven't memorized the quirks) will login to their account and then wonder why the forums still don't work - "Oh, there is another login form further down the page!"
Most of all (and I have never really understood why this absolutely critical feature is missing):
- The ability to identify (and search for) which WindowBlinds skins are for which version(s) of Windows and which DeskScapes themes require MPEG2 support and which don't.
The days of having to waste hours and bandwidth downloading a ton of promising stuff, only to try it out and find it doesn't work, should have been over a long time ago.
I would add fields for this critical information that are mandatory and not allow skins/themes to be posted until the artist states which configurations they have designed and tested for. Currently posted skins/themes should be flagged and the artist pinged until these fields are completed. This would go a long way to addressing the chronic shortage of skins for 8, as people will no longer be able to coast along pretending their XP-only skin cuts it.
I realise the downside is that the apparent number of skins available will no longer be grossly exaggerated (the claim of 100's or 1000's is empty if almost none of them work for you), but it is a pain worth bearing in the long run.
