Editable common properties for group of entities

When you have selected N items that are all of them items of the same type (meshes, effects, sounds, ...) it would be helpful to be able to edit a common property like "Show name", for example, at once. Instead of having to go through all the list and changing that property manually.

Edit: If the property is common even though the items are not the same type, it should be editable too.
