I have never used them before. I can easily manage states with buttons and functions, changing visibility and so on, without setting up a workflow system.
So, now, in version 8.0, is there any advantage in using it ?
(PS: I'm a developper more than everything else, that can explain if I miss something else here...)
To be honest, I've never seen this Graph view of workflows. I found it because you suggested it, and I thank you for that. I think you should convert your comment as an answer.
No problem PY, hope this helps you. :) I've converted my comment to an answer as you suggested!
