Using 1.12.3
On open the graphical query builder, leftmost directory panel opens with
database as main item and Catalogs and Schemas as sub-items.
On click the + control for schemas to open that item "public" appears,
but the + control for public does not appear until you double click it.
After the double click you can open public and get to the tables and
indexes and so on.
It would be helpful if on click the + of schemas that when sub-items are
displayed that the + control would automatically be added.
The same behaviour would apply to Catalogs.
