Sorry if I missed something. I did go through the docs and tried some searches...
I started creating some classes, interface and connecting them and I noticed elements are render in a single line on the canvas.
Take the two relations below. The second will be painted to the right of the first. If I keep adding, there will be a very wide and not so tall image (weird width to height ratio)
MyInterface <|-- MyClass
MyInterface1 <|-- MyClass1
So, can I make it the second relation show under the first relation, basically draw the uml elements on multi lines?
