Hello OP here. Actually drag and drop isn't implemented :) You can only drag and drop onto the trash to delete a task or a category. Also, when you input a calendar event, you can start by the date (eg. 16/04/2014) so that they get sorted automatically. I built this because I didn't want to have sensitive tasks saved in the cloud. It's just saved locally, and you can backup to your drive if necessary (or even to dropbox if you really need cloud backup). Any feedback is welcome!
