I'd like the ability to email a task to someone so I could check up on them periodically. In other words, I have a "Waiting list" and rather than having to email them, type int he main issue of the task and then ask them how progress is going, I'd like an "email" button that I could simply type their email address in and send it to them.... (This would work really nicely with the gmail contacts suggestion too, but isn't reliant upon that.)
