I have been playing Simpleplanes for a while now (stuck on mobile because i bought it a week before the PC version released) and I have saved a large number of planes from the community and I realized that the plane list gets very hard to use with so many planes, so i thought that a good idea would be to have a way to create folders for planes so people could sort their planes into folders(bombers,fighters,civilian,gliders,commercial,futuristic,WW2,helicopters,boats,cars,etc.). I think this could really make the game better for everyone.
