Really happy to hear that you will be working on plugin! I was elated when I first installed it. Only page speed related plugin installed, and I got a 99 on mobile and desktop first try! I was willing to ignore the 403 issue with Google till I found out that any link clicked resulted in a 403.
Hope you are able to solve the glitch without hurting the performance as I would love to use just 1 plugin instead of 4.
Thanks,
Stephen
