This repo has the source code for PlantUML Gizmo.
You can submit issues, requests and comments on this GitHub repository.
The PlantUML Gizmo Add-on was created initially (2014) to help students easily put (and reuse) UML documentation inside their laboratory projects in software design courses at the École de technologie supérieure . It was one of the first Google Docs add-ons, and took 6 months to be approved. It's been used by Google's Android and Pay teams (I've interacted with their engineers).
This project was designed and coded by Christopher Fuhrman with help and encouragement from Arnaud Roques and the crew at PlantText.com (Arwen Vaughan).
