The Garrett IA concurrent set shape is missing. It looks like a half circle. Here is a link that shows what it looks like: http://www.jjg.net/ia/visvocab/#setAdditionally, the shape that I had mentioned before that is also missing is the process shape which is a rectangle with clipped corners. To see an example of it, please look here: http://www.jjg.net/ia/visvocab/#flow These shapes have critical meaning for people in software and user flow development. If there's a way for you to add them quickly to your system, I'd be very appreciative. Thanks!
