Is there a way to indent tasks on android by holding and dragging. I can move a task above and below an adjacent one but I can't indent. I have to use the edit task and task level to make a task indent. It's a bit cumbersome for me.
Unfortunately, that's not possible - you can't indent a task via drag & drop. We may consider adding such option in the future, though, and you're welcome to request it in our Votebox: http://todoist.com/Vote/
