Always show parent task if a subtask is visible in the view
Add a display option to show a parent task if a subtask is visible but the parent is filtered out.
In other words, the subtasks will always be displayed indented below its parent, even if the parent would otherwise be invisible.
Alternatively, display the "path" of the sub task. So if my hotlist for today has me doing a water change for my fish tank and cleaning the carpets as parts of bigger tasks
* clean house
- vacuum (visible in current view)
* fish tank
- replace filters
- test water
- water change
> vacuum (visible in current view)
Then l see
* clean house : vacuum
* fish tank : water change : vacuum
