[appigo-todo] new features for todo

Hey,

I love this app. It is very easy to use and has great features in
being able to make tasks either single tasks, projects or lists.

One thing I would love to see on this app is, to make it have it's own
calender. So you can make appointments and tasks and see them on one
calender. This is one thing that is stopping me using this app to
it's full capacity. I know it syncs with iCal, but the tasks don't
show on the iPhone. If it had it's one calender, you could see both
tasks & appointments. If you wanted you could disable this function.
This would make it the best app on the itunes store.

Thanks so much,

Smylie
