I love how simple it is to use in general . I learned it in about 2 hours.
I only wish for one thing (at the moment!) and that is to be able to make arrow-LESS connectors both with solid lines and dotted lines on the same diagram, rather than having it be a global preference. I know that I can label relationships, but that is an extra step and not as visually effective as being able to use different styles in connectors. If there is a way and it has eluded me, let me know.
