Hi devonkim,
Thanks for checking out Isoflow, I'd love to know more about how you use diagrams in your work. The intention is to take Isoflow in the direction you're describing (i.e. being able to show different processes on top of the same diagram), so would really love to get your thoughts on what you think are the most important aspects. Please reach out to me through the 'contact' tab on Isoflow if you're up for discussing further. Thanks again for the feedback.
