Find context menu missing

[skiwi]

Why is it that in a diagram some entities have the Find in Project Browser content menu item, and some dont?

No find

With find

I hesitate to use the word consistency, but would be happy to suggest that usability would benefit

Because notes don't appear in the project browser and EA knows that the command is useless.

OK, well here is another example.
Where diagrams are in other diagrams!

Also in the situation where an element is linked in a diagram to an element in another diagram the find context menu is missing, for example in the following, all 3 elements are created by Copy, then Paste | Element as Link.

What I want to be able to do is find out where the elements are used,
not an unreasonable request I would have thought.
