2.) Using the on screen buttons
a. edit a task

Thank you Clyde,
Speaking from sake of usability — it would be a good idea to place button "add a subtast", because now its too complicated to place the first subtask.
We'll take that into consideration. I myself prefer keyboard shortcuts and once you have gotten used to it, it will be fairly easily to move around your task and change there levels.
