Gmail productivity tip: Superstars for keeping track of ToDo's

To get a grip on a busy inbox, keep on top of important emails by giving them Superstars.

 - Generic Star

 - TODO

 Completed

 - Waiting for response

And with multiple inboxes in Gmail, you can have one of those inboxes just for showing messages with one of those stars. So 5 entries from my TODO list sits above my inbox. That way I'm always atleast concerned with keeping on track.

There are other stars, but I haven't felt that they make more any more productive. Maybe as I have even more plates to balance.
