As I created more and more planes, I began to find it tedious to scroll through the large list. And if you're the kind of person who downloads lots of other user's planes, you know how long that menu can get.

The search bar helps, but I think it would be more convenient if you had the option to categorize your creations into some kind of sub-menu folder-like system, so you could quickly load up the creations you're looking for based on exactly what the creation is, or is meant for.
