Hi!

I think it would be a nice and fun feature to be able to sync tasks with Google Tasks in stead of Google calendar. This would allow:
- syncing with google calendar (as is already provided)
- checking off tasks within the calendar/gmail/gtasks
- keeping separate lists of tasks in Google Tasks, equivalent to projects or contexts (preference option?) in Doit.im
- adding new tasks to the doit.im inbox from Google Tasks (gmail/calendar) without needing to send emails
Another app that syncs successfully with Google Tasks is GTasks on android. Maybe you can look at how they did it to see if this is something you'd like to implement.

This feature request is fun, but less important than the ones I submitted previously (http://help.doit.im/topics/5296 and http://help.doit.im/topics/5510).
