I think that a great asset to confluence would be built in reporting, the ability to view a user's contributions without having to go through hoops would be a great addition to confluence as well as other types of reporting. such as a full list of pages a user has edited as well as their revision history, Probably all things that can be done via cryystal reports, however supported natively by confluence would be a great tool

A lot of the 3rd party reporting plugins for confluence are great, but do not work as expected. A Feature native to confluence would be much appreciated
