My problem is that I have a lot of actors and participants.
So it makes a sequence diagram with very big width due to participant's text taking lot of horizontal
place
I made some tests and to optimize width of diagram while keeping participant text easily readable, the best would be to be able to write vertically on one line.
So needed is :
skinparam ParticipantFontOrientation "vertical"
skinparam ActorFontOrientation "vertical"
