It would be nice if users were allowed to select which development stream they want to be a part of.
Stable will obviously not become a thing until the 1.0 release, but when this happens it would be nice if we could choose whether to sit on Stable, Testing, or Dev software streams. With obvious caveats for buyer beware if you are in Dev or Testing streams. The number of users at sign-up suggests there are a lot of tech-savvy people here. This community could be leveraged in the form of much wider testing than is currently possible.
Would also be neat to have a few more Blog updates than at present. Perhaps monthly? It's not a great feeling having paid for something, then getting sparse updates on how things are progressing. The way Immich presents it's Roadmap is very nice while keeping everything simple.
