I often realize that I want to place a bounty on a question, but already have a bounty in place. So far three simultaneous bounties have been allowed, but I find I forget many times which questions I wanted to feature with a new bounty, when one of my old bounties is done. A bigger problem for me actually now is the two day wait; I know I will want to bounty a question because I'm either not getting an answer (non-Meta), or will want to draw attention to the question (Meta).
Could we get the ability to queue up a bounty so that when our one bounty is awarded the next takes its place?
I would think we'd want some kind of confirmation in case our mind has changed, maybe it would cancel if a new answer is added. Even a queue just to send us a reminder would be nice.
