Sub Task Feature Query

When we finish all tasks in the sub task, the parent task also gets marked as completed. Is there a setting to disable this. Reason being the sub-tasks under a parent task are all closed now but may be added in future. So, I would rather just have the parent task still visible while all sub tasks are closed.
Is there a way to do this.

I wouldn’t have mentioned it, if you hadn’t done so, but I find this feature more of a nuisance than a help. However, I do like how my calendar disappears (pretty much like my life)! The days go, then the months and [gulp] the years.

Yes, see under Settings. Uncheck the option “Close parent task when the last child is closed.”
