Long time TF user here.
I use FoT so much I won’t upgrade past version 1.8.0, the last version with your implementation in it. I know, crazy!
Anyway, it’s been a while since you addressed this. Any chance you’ve been able to work on reverse engineering it?
Your implementation of FoT is way more useful than Apple’s.
I haven’t updated to High Sierra from Sierra yet. Going to give it more time.
Thanks for keeping TF going.
