it would be great if we had objects per layouts view.
then we would just drag 'n' drop repeating objects to the layout 2 folders, and those which do not repeat would stay in the first layout only. of course on export they would be all the same object (grass in layout 1 and layout 5) still exports as 1 grass texture.
currently you can only create lots of folders and stuff, but that doesn't make it cleaner :/
