Filter methods out of diagram

 Hello,

Is it possible to filter out artificially constructed methods in diagrams?

I am trialling IntelliJ Ultimate with the aim of using its diagrams feature to enhance the visibility of the architecture.  However the list of methods for each class is swamped by methods such as "copy$default$1()" which are artificially generated and of no interest.  This greatly decreases the focus, so I want to get rid of this junk.  A text filter would suffice.

BTW, other architectural tooling would also be of interest.  It won't remove the need for good diagrams but would interest me! :-)

Many thanks, Max
