I'm personally waiting for a tool to group and split mails in a mailing-group-compatibile tree view. Or at least something respecting the usual headers mailing groups use to mark which mails belong to which thread (so that when you change the topic the e-mail doesn't go to a different thread in GMail).
Not that I care about it for 99% of my conversations, but one Hackerspace I subscribe to seems to be stuck in 1980s Unix Land, and get terribly annoyed at people using GMail for mailing ;).
