This reminds me, it would be nice if Google had an easy way to blacklist a sender and/or subject such that it wouldn't even go to spam. I have enough spam false positives that I needed to scan my spam folder periodically, and I'd love to have a way to permanently filter out regular crap in there. I've created explicit filters for some of the more prevalent ones, but a one click blacklist button on spam emails would be great. (Along with some way to edit the blacklist in case of mistakes.)
