The pokemon boxes also need an overhaul which would allow you to easily order your pokemon by type, number, level, etc. and also be able to manually move more than one at a time.
B2W2 has those fancy icons in "Move" mode - 3 icons above the pokemon list that change interaction style (A calls menu => A grabs pokemon, drag-n-drop is enabled => A triggers multi-select mode). Those can be changed using Select button as well. As for sorting/search see the magnifying glass below pokemon list.
