Thanks @arieljalali. We have gmail plugin definitely on our roadmap.
We are also thinking whether we should be make a Chrome extension that allows assigning tasks, requests or questions from your inbox but also, let's say while you are adding an event to your GCalendar, discussing something on Redpen or collaborating on a Prezi. I am curious to hear your thoughts about that.
Looks like a dead simple approach to a universal problem. Make a Gmail plugin and get task management out of email. Also good domain name but it doesn't convey what the product does, which is super useful.
