Agreed, if there is one improvement that has been long, LONG, LONG overdue, it is the way the content browsing is handled.

The ability to scroll and just the basic need to return to where you were in the list (as opposed to jumping back to the top half the time like Mask2 mentioned) would make life substantially easier.  

Small improvements to the content browser would have a more immediate effect on the entire community then half the fancy crap that was added for P7.

And screw if being in the next release of Poser, for the love of all that is good, could we please have this addressed in a service pack release.  It's just embarrassing!
