Thank you! 
Yes, that is much, much better! I’m a beginner in all this and it is confusing enough to try and understand multi-level Bayesian models. And then I also have to worry about low-level details about Cholesky decompositions, matrix unpacking, etc. which makes it really difficult to understand what is going on. So I greatly appreciate that you are simplifying the API!
I don’t mean to rush you, but do you have any idea when this will be released? Are we talking 1 week or 3 months?
Thanks!
