Hi!
I have been using Doit.im for a bit now and being a Web Developer I wonder whenever there every will be a public API.

This mainly because there are some features missing which I would like to see added myself
for example:
Daily an overview of what I have to do or forgot the other day;
localized reminders about tasks that are important
-> this could be done using Android Llama/Tasker and would be super-handy!

I must admit that having an API will motivate other developers to create third-party-apps, integrate doit.im in their own app/services etc... And for me personally, access to an API would be the biggest reason to pay for the service (though the price you guys ask is very good and honest!)
