I am Shelby Moore III, also known as "AnonyMint" at the Bitcointalk.org (BCT) forum where I was an early proponent of anonymity in 2013. My analysis is watched by many 100s if not 1000s of readers at the BCT forum. My current username there is "TPTB_need_war". I have invented some zero knowledge cryptography (combining Cryptonote one-time ring signatures with the Compact Confidential Transactions for homomorphic value hiding). Roughly a couple of months ago, I abandoned that invention and proclaimed that all anonymity designs were futile except for Zerocash, because the meta-data correlation problem was insoluble (impractical for mere mortals to work around on a regular basis).
However, I still see fundamental problems in the Zerocash direction and I am proposing at least one solution. I would urge the developers to read the following threads (especially from the linked posts forward) and please respond here or there to the major issues discussed.

I presume you know how to click the quotes in posts to venture off to the source threads from whence they originated in order to find all the discussion that has transpired today.
Note there are even legal criticims of the conjectured ROI model of Zerocash (z.cash). Hopefully you can address those as well.
Be forewarned you are will descend into a hornet's nest of ad hominem and speculator turf battles noise interleaved with attempts to stay on technical focus.
