[Feature Request] Hide Header when all tasks in category complete.

[MinoWizard]

Previous versions of DailyDuty would hide the header text when all tasks within their category were completed. In the current version of DailyDuty, headers remain even if all tasks in that category are complete.

For example's sake, the below image shows the Special Tasks header remaining even though there are no available tasks underneath it.

I'd like a checkbox to re-implement this feature of hiding categories when all tasks are complete.
