Suggestion: Swipeable notes
When I add a task in the vein of "pack my traveling bag" I of course want to have several sub-tasks under it. In my experience this is very cumbersome to add, at least in the android app.
The easiest solution to this I think would be if the notes on a todo would be swipeable. Adding several notes in succession is much faster than adding several sub-tasks.
This is the one and only feature I miss from Any.do (which I used before I tried Todoist).
Otherwise it would be nice to have a feature for adding several sub-tasks at the same time.
