Currently, backpacks and blufor vehicles and backpacks both begin with "B_". This is a minor inconvenience. While it's not terribly difficult to tell a backpack apart from a vehicle, it makes it hard to quickly find a backpack in the alphabetically-sorted config viewer, makes the "B_" section much larger and brings two unrelated categories of things together--"neutral", non-unit, wearable backpacks and blufor, playable/drivable vehicles and units.

Speaking of large lists, in the config viewer at my resolution (1920x1080), the "B_"s take up 3 and 1/2 "pages," compared to the "O_"s, which take up about 1.
