It seems like the only thing that doesn't function when using the full site on the iPad is reordering by dragging. Will that be fixed? Is there a workaround in the meantime?
unfortunately, the full Todoist version isn't optimized for touch-screen navigation, but we will consider adding such feature in future development. You're welcome to add a feature request to the Votebox:
In the meantime, the only workaround is to either use our mobile site: http://todoist.com/m or - even better - our native iOS app: http://itunes.apple.com/us/app/todoist/id476672770?ls=1&mt=8
