Also, how are they calculated?
The "Most important" rank would be renamed "Looking for feedback" or something like that.
In the bugs there are several levels of severity that (I guess) help pushing bugs as more important. With enhancement requests there is only one level though:"enhancement".
So I was thinking of playing more with the Priority field, currently quite unused (except on product Website). That field could mean "priority for feedback" and we could set it High to push reports to the Bug Jar for feedback...
