Foregive me if I'm missing something, but suppose I would like to look at 20 bugs, and change the priority of 10 of them to any arbitrary priority (that is, not all to the same priority). The bulk change UI forces me to change them all to the same priority. If I could just get the list, then have drop-downs in each row to change the status, then hit Save and change them all, that would be helpful to me.
