Fantastic function but unfriendly interactions – Grafio 4 - Diagram Maker Review

I love this app. It gives me the exact graph drawing capabilities I’m looking for. A few wired/awkward interactions when: 1. Rename a file. 2. Not allow to change a shape’s setting, like the size and type. Feature request: 1. Export the graph to dot file, xml, or graphml. This app has a huge potential. I hope to see it getting better and better. Thx
