What would you love to pay for if it was available?
khafra: A combination proxy/script/something that'd pop up an interstitial task tracker/to-do list overview when I go to any of a list of "time-sink" sites.  I can click "snooze" and go to the time sink, with the task tracker popping back up after 5,10,30 minutes, turn it off for a day or two, or click through to the detail/edit view for any task and get to work.
