I would prefer we try to keep the interface here as simple as possible. Supporting alternative embeddings would be nice, but I agree that it would be better to handle...

I don't really have the bandwidth to think about this right now, but I'll tag the other Manifolds devs @kellertuer and @mateuszbaran

Thanks for the issue! I'll need to make a detailed comparison with the paper to be sure, but this indeed looks like it could be a mistake. Would be nice...

Fixed by #29

> Does Pathfinder interact with the AD backend chosen in Turing, ie.., `Turing.setadbackend` ? Good question! We use Turing's implementation of either `optim_function` or `optim_problem` (both are exported but not...

Thanks @SamuelBrand1 for the bump! It seems LogDensityProblemsAD and Turing (as well as Optimization.jl) now use the ADTypes interface for specifying AD, so that's a good reason to adopt this...

@SamuelBrand1 #178 adds an `adtype` keyword to `pathfinder` and `multipathfinder` for use for Turing models, LogDensityProblems, and log-density functions. Still need to update the docstrings and add a few more...
