Number on tab for open Subtasks

[#1]

Can a number be added to the subtask tab that shows the number of open subtask (basically the way the issues tabs functions)? This would save time to show why parent tasks are open or to quickly differentiate tasks with and without subtasks.

[#2]

This would make the Subtask section act the same way other sections like documents and issues work - leading to a more consistent user interface.
