I would like the Wikibase web UI to show, on the page of a given entity A, the applicable statements that are inherited from their parents (superclasses or superproperties) B, C, etc. This could be implemented as a new gadget.

• Plus 1: An inherited statement should be overrided when it's identical to another statement that is explicitly defined in A.
• Plus 2: The statements should not only be inherited from the parents B, C, etc. but, transitively and optionally, from all the ancestors.
• Plus 3: Multiple statements whose claims are identical should be merged in the UI, listing all the references, inherited or not, in a single combined statement.
