Also, something which i suppose was asked lots of time: an vbulletin like egosearch. It's the list of all the topic subscriptions. It's extremely useful to see which threads need your attention.

I would say the buttons to hide all the modules in the homepage. I never need to see the online list, so I would love to be able to hide it. Also, the "latest images in the gallery" panel in the homepage. I would love to be able to disable it, because I hate having useless things occupying space. Obviously I'm talking from the point of view of an user, non of an admin, otherwise I would do these edits by myself... :D
