Individual "View-Area" for each Diagram
Imagine the following situaton:
Multiple diagrams of different complexity and size are opened.
You have to work with all of them (add an element in one, look up something in another one, modify a third one, ...)
At some point you won't be able to work with the diagram if it is completely visible. So you zoom in to view only a specific section of the diagram.
Now, if you switch to one of the other diagrams, the view-area stays in this exact position/zoom-level, even if the new diagram is
vastly smaller (or even empty, because its a new one) than the previous one, so the viewed area may be blank.
I think it would be very useful if the program remembers the selected zoom-level/"view-position-offset" for each diagram individually.
Or at least resets the viewed area to default, if you switch between diagrams.

sustain this idea.
But not: "Or at least resets the viewed area to default, if you switch between diagrams"
