Agree on removing the back packs and similar bags from the play area. I also made play stations and that has helped a lot in the sense that if you want to play with the dolls you have to stay in the doll area and if you want to play with the barn you stand at the table that has the barn and animals on it. That way you have to actually pick what you want to play with and are unable to hoard stuff from another area because you can't leave the playhouse or block corner with any items from there. Each place has some crossover items for imagination so what is in the space stays in the space. A lot easier for clean up too.
