I hope this was not already mentioned, at least I haven't found that with a quick search... (or at least not EXACTLY that...)
I'd like some more filtering options in searches, presumably to be taken in account AFTER receiving the file lists form servers or peers (I suppose the protocol doesn't allwow them natively)
Basically the option I'm after is the ability to EXCLUDE results by words in the name or extension (like, search for Video and exclude .wmf) in order to reduce result lists sometimes too great.
And, of course, I'd like to see all the actual and future search options ported to the web interface... I hope the PHP version will soon catch up at least with the previous chicane
