Alert Dialogue when trying to delete a collection that has objects shared in other collections!

Hey guys!

As the title suggests , why don't blender notify me when I try to delete a collection that has objects shared in other collections!

Plus:

I hope there is an option to only delete the objects that are not found in other collections!

This will make our lives easier!

Another idea is to add a " select unique objects" option in the menu that pups up when you right click a collection in the outliner.

Cheers
