Re: BuddyPress-Links 0.3 FINAL is here at last
Sticky link is a really good idea. I think I will add that one sooner than later.
List in multiple categories is on the long term development time line. Some time in the future I will be attempting (again) to switch the categories to the internal WP api which is almost impossible to hook into, and at the same time I will be adding tag support. This is going to be a while though.
