It would be great to see that the pinned sites functionality (with jump list tasks) of IE9 within windows7 would be supported. This allows win7 users to see instantly that tasks are due. I for one think that this is better than whatever app you come up with since you don't have to open it to get an idea of the tasks that are due... + its easy to integrate!
