Show an icon if a task has sub-tasks or notes
This is a very quick Thing to realize:
It would be of great benefit if you indicate if a Task contains subtasks or descriptions. It would help me greatly to keep oversight of my lists.
Very often I have lists that are mixed of plain tasks and tasks with subdescriptions.
To keep track, where I have a subdescription, I add "(see Task description)" to the title of the Task. This is sort of annoying and could be solved by indicating via an Icon, if a Task has subtasks or descriptions.
