Why do all entities need to be in a single diagram?
It would make things more modular and readable if one could create like 3, 4, or 5 diagrams to represent the Domain Model.
For example, in MS SQL Studio, I can create several ER diagrams and a given entity can show up in more than one. No problem with that.
That way, one diagram can focus, for example, in the Product entity and some entities related to that.
Another diagram may be concerned with Company entity and its context.
I have made a similar suggestion here: https://forum.mendix.com/link/ideas/2032
That would actually be great! I´d love that to as I´m often completely lost in my diagrams...
