Show persistency of an entity in the Entity Access Overview in Module Security

The security overview per module is a very handy summary of who has access to which entities (see screenshot below).

Ofcourse, you need to be careful with granting Full write access, especially for anonymous users. When the entity is not persistent, it is less dangerous.

To have a clear overview, it would be nice if you are able to identify whether the entity is persistant or not. A simple icon would be sufficient.
