I've been using this for brainstorming/planning and mostly loving it. There's a little bit of a learning curve, and some things I wish it did differently... But we are using it more and more instead of shared Google docs / screen sharing
One thing I wish it had was a comments feature so that people could leave feedback on a section of the diagram
Sweet! We're actually prototyping comments and getting feedback on those mockups and prototypes right now. If you're up for a quick chat about pain points and the comments feature, please reach out directly, I'd love to chat. I'm doug at plectica dot com.
We've made some tradeoffs between flexibility and constraints/structure here -- any feedback is most welcome!
