Subtasks UI improvement suggestion

[biphasic]

Hello, many thanks for this great application. I suggested a UI improvement in the past and you kindly took it up so I thought I'll make another one. When one has many subtasks, it takes up quite a lot of space, as the indicator 'subtasks' takes a line by itself, as shown here:

Instead, maybe it's not necessary to say 'subtasks' in its own line but simply include a counter at the very right of the parent task. That way the parent task has a counter at the very right which folds/unfolds the subtasks. I made a quick mockup:

Thanks for your work.

the spacing between parent and subtasks is obviously too little in that mockup, apologies :)
