Note that this is not exhaustive, and may change!
We are also working on more long-term features, like the much awaited quote posts, but those need some preliminary protocol-level work before we can start the implementation.
Please remember that the core team is very small, with only one developer! Many of those features are contributed by various volunteers, but we also work on fixing bugs and improving many non user-facing features (performance, security, admin & mod tooling…).
