The focus is on time based tasks right now, my idea is automatically building tasks by finding and extracting times. At launch it'll probably be a case of copy/paste emails in and get tasks added; the obvious next step being adding by forwarding an email. I'd almost be in a position to get a demo working if it weren't for exams :)

You're definitely right that there are other options, and I'll be reconsidering that approach closer to the time based on what's easiest/most important for actual users. Thanks for the comment :)
