I have some suggestions that I would love to see implemented in the UCP in the future; these suggestions are both original and derived from other forum software. I hope to see some added in the future! UCP Layout
I don't think the tabbed layout works that well with the UCP. I like the fact that there are tabs, but I don't like the fact the layout revolves around them. I like the old style of the left-hand-side options. Possibly some AJAX for expanding and contracting them, and maybe still use tabs a bit? It's sometimes complex to understand which tab something is on (profile & settings get confused alot) etc; also, make common features accessable easily (possibly an optional dashboard?) Profile Field Privacy/Private Profiles
I've noticed this feature in vB, and I fell in-love with it. I know that IPB is trying to stay away from becoming a massive scattered social network platform, but this is a feature I see as very useful; especially in the area of hiding contact details for only friends to see; and for preventing ignored users from viewing areas of the profile/posting messages. I strongly support implimenting this into IPB3
Those are my main concerns, also, there are some posted on this thread (CUSTOMER/STAFF ACCESS ONLY, SORRY).
I hope to see these added soon!
