This thread is arguably the best “state of Flux”/roadmap I’ve read 
. Using Discourse, Slack, GitHub and Zulip questions as a sample, eliminating opaque/unexpected errors with the new AD would go a long way towards improving UX. That said, there are still many architectural sharp corners in Flux that could use filing down. (e.g. anything RNN-related). It would be nice to get the model zoo out of purgatory as well so that folks actually have a working reference for anything more complex than a Chain…I created a “pre-triage” issue for it on the tracker, but perhaps that should be expedited.
Edit: the ~30s load time could use a dramatic improvement as well. TTFP was a great success, so given how many dependents Flux has reducing TTF gradient would be a significant QoL improvement as well (long CI waits come to mind).
