In many cases we use the documentation-tab in an entity to describe some useful notes about that entity.
This can be why the entity is created or some info about some attributes or ....
The problem is that you always need to open the entity and navigate to the tab documentation before you can see if there is something written in there.
It would be nice to have a visual marking in the entity itself.
This can be a very simple * in the right-corner of the entity in the domain model
I know that we could also use annotations but we can't link those to the entity itself, there is no annotation-flow possible in the domain model and domain models are on there own already sometimes very full
