need to track 6.1 status of resizing to be solved somewhere later:
sometimes some parts of long attributes or operations need to be hidden or attribute/operation compartments need to be
hidden completely. the only option in this case is to resize class node. but after most changes affecting the class
class switch back to full size, when working on big diagrams it may require to readjust size again and again multiple time.
global options never expand or contract do not help because it's not good as default option for long work.
other way to solve the issue is ability to limit attributes/operation/names length, and completely remove
attributes/operations compartments also isn't implemented. but may be it still will be good to have ability to have size
below content in some cases.
