- Visualization tool bar is empty. Afair there were some buttons
- Please add a possibility to export / copy diagram.
The tool bar works fine in latest version. It should be resolved.
What about #2 - possibility to export / copy diagram?
Sorry for missig that question. Yes, you can click print and save the file as other format
Or you could do a copy (ctrl+c) and it will copy the current diagram as an image.
