I agree that Creo is better in some ways for dwg. I don't know why they had to break a tool that was working so well and then let years pass without fixing it (they broke it in WF5)
Look at the product ideas that I updated the links on above.
Basically, you can no longer show all dimensions/datums/notes that are currently not shown within the show dialog. You can only show 'annotations' that have never been shown, or are deleted. You cannot show erased dimensions/annotations! All they need to do is allow erased annotations to be displayable in the show dialog (formally show/erase dialog).
