Most issues and progress for Fedigardens is tracked in our Jira Cloud instance. However, this isn’t accessible to the public, and you might be interested in seeing where Fedigardens will go next.
Thankfully, we do have a page dedicated to potential things on the roadmap suggested by you, the community. You can view this in the Fedigardens tag on the Feedback Portal. Anything marked as “Planned” or “Tracked” is considered on our roadmap.
