Display the amount of subtasks a task has beside its title

[doitux]

Is your feature request related to a problem? Please describe.

In some situation it would be nice to see, if there are collapsed subtasks in a task or not. Especially when reusing a big tasks with many sub and subsubtasks for another time it could help to find every sub task which is maybe hidden

Describe the solution you'd like

Maybe it would be possible to display the number of all subtasks of a task in parenthesis beside the task description like
Task1 (3)
Subtask 1.1
Subtask 1.2
Subtask 1.3

Describe alternatives you've considered

Another alternative for finding every subtask when reusing big tasks for another time could be an "expand all subtasks recursive" button.

@doitux, I think the title should be Display the amount of subtasks a task has beside its title.

We have an icon indicating that a task has subtasks that are currently hidden.

I had situations where this indicating icon is not displayed even when there are subtasks. Unfortunately in cannot reproduce but it could be a combination of closed tasks which are reused (clicked to open again) and the end-date display which could cause this.

Here you can see it:

When i click on "Programmplanung" the subtasks appear:
