How to display the entire package?

[Ericga]

In a class diagram we can display part of the class package (ex: package::class) by checking the Show Namespace in the diagram properties but that does not help when we have names like:
dt.cms.schema.Group because only schema::Group is displayed.

There is no way to know what we are looking at (we have dozens of diagrams, hundreds of packages and a bit over 10000 classes). Diagrams are usually small but can include classes from many different packages.

This is an obvious dumb question but I searched diagram properties and options to find where to enable displaying the full name and not truncating but could not find where it is done.  :-/
