What would make it better is your extra space idea except what if the main drawer was sectioned like A was clothes then had a subset, same with flooring, furniture, and a misc one. Each would have the amount of space as what there is now for all so just upsizing the main one a lot in an organized way as I already try to put similars together and clothes until get Gracie and don't need museum holding tons of different types anymore...or is that just me lol. It was nice when I decided after that if reorderables sell if not well I have tons of extra special sets and such should probably sell off don't need so many coffee beans in letters, or mush and spooky sets and other doubles.
Anyway a larger but organized compartment would be good as at start you need more than later in.
