"Hierarchy query devices by default use checkboxes. It would be very helpful to add Select All and Deselect all options for the checkboxes at each level of the hierarchy.
For large hierarchies e.g. 3 levels of 10 nodes, it is quiet time consuming to go unchecking boxes to drill down to the lower layers of the query device. Image and 4 layer hierarchy with 30 nodes at each level.
I guess you can use some of the original query devices to narrow your search but this is a bit of a cop out. If we have a hierarchy query devices it should be usable (standalone)."
