If your scene is hugh and have 1000's of objects and you need to update / replae some and want to delete the old one from inventory it's nice to know if you can delete it by a indicator on the objects that are not in use on one of your scenes.
Request: Some indicator when you delete some object that tell you if it's still in use on one of your scenes would be nice. Mabye the request can be solved in different way i dont see right now.
Option to take item from your scene back into inventory mabye solve this problem to. SO you have at least the object back. without a new required upload.
