Hi Pete, please let me know when that is finished.
Also, I have a suggestion for you, and it could help your business. I have worked with someone and implemented inline critical CSS, as well as some other changes that greatly increased my site's speed scores in google: https://developers.google.com/speed/pagespeed/insights/?url=https%3A%2F%2Fwww.celiac.com%2Fgluten-free%2F
I used to score in the 30% area, and it was steadily dropping. The fact is, IPB doesn't give a crap about their users' google page rank or they would have done something about this long ago. You as a skin developer could offer certain to differentiate you from other skin makers--site speed skins. Just a thought. My site now scores in the 75% - 85% range in google speed tests, and as a results my rank is going back up:
