Dragging and dropping tasks is not smooth or clear where the task is going sometimes. Especially when you are trying to drag something into a subtask position or from a subtask position back out one level. There is no quick action to go back one level, instad it's just "convert to task" or "convert to subtask" but there are many layers of subtasks in my lists so I have to drag and drop instead.

It's very jumpy - I want to move my level 2 subtask up one position above another level 2 subtask or from level 2 to level 1 subtask and it's like the system gets confused. It's not simple at all. It needs to be as smooth as google sheets, really. That's the ideal.
