-ability to edit multiple scenes at the same time -resource internal IDs are now persistent, this makes multiple scene editing possible but maaaaay result in file corruption bugs (tested and could not find anything but possibility exists because core code changed, report immediately if you find this). -properly save settings, layout, etc when edited -script editing is independent from scene editing now -show a yellow box when a script belongs to the scene
