We are also very involved with continuing development. GitLab provides a very nice set of communication tools via issues. You can visit the main project page on GitLab or go to the individual issues pages for the Arduino project, the Android project, or the Jekyll project. If you see a bug or would like a feature, please start a new issue (or let us know in the comments of an existing issue).
