One of the biggest issues I have with the game is I have hundreds of vehicles and engines and etc in saved vehicles. While the search function is handy (assuming I can remember the name for the vehicle I want), it would be really nice if the game supported folders within saved vehicles.
That way I could have a folder for planes, and a folder for boats, and a folder for custom engines, and so on. Maybe even sub folders so I could have a sub folder for rescue boats, and for fire boats, and for tankers, and so on.
So maybe we could have folders to better organize things (plus maybe even 1 layer of sub folders). These folders could use normal windows folder structure to keep things simple
