Great questions! Public and private groups on Nostr have been a major pain-point with many disparate implementations, none of which seem to fully meet the needs of users or provide a genuine alternative to Facebook groups. Solving that was the main goal of this project.
While I focused mostly on the process of creating Chorus in this post, I'd love to do another deep-dive into the implementation we chose and why, how we expanded NIP-72, and the future plans to improve and grow it.
In the short term, I can tell you that the nostr:nprofile1qytzqamnwvaz7tmyd968gmewwp6kytmjv4kxz7gpz4mhxue69uhhyetvv9ujumt0wd68ytnsw43qqgza8ytsd95h3un5lqdc2dxaenmumnj6ts9xnw53l2ulpe2rdd9tkyrf6f92 team definitely has plans to keep working on this client! I recommend checking out the "Future" tag on Github for a list of the things we already know we want to do, and we welcome bug reports as well!
