An addition for Child Reports that shows only one result per Notes Category, along with the number of notes in each category, would be incredibly helpful.
It would also be great to have a second parameter that allows the report to be run with the names/details associated with a selected category. The user could then quickly identify categories with the fewest notes, review the records attached to them, move those notes into the main category, and delete any duplicate categories. This would make category clean-up much faster and easier.
