Agreed! For example, have a category for "Cleaning" with sub categories "Front of House," "Back of House," "Outside," "Restrooms." Or, have a category called "English" with all the English translated labels in subcategories, and a second category called "Español" with Spanish translated labels in those subcategories. Also, ability to drag and reorder the categories and subcategories.

maybe even be able to color code those sub categories so people can easily find labels in a group
