When selecting a classification for an item (using the MODERN "classification manager") it'd be helpful to be allowed to search for classifications. When your classification database has 50+ classifications in multiple levels, it can be difficult for a less-familiar user to find what they are looking for. A simple filter or search bar could save tons of time and improve accuracy in finding the right class. It would also be necessary to search for attribute values, most of the designers know the value from classification attributes by heart.
