Hi Steve, Yes "in coming months" sounds good, that will let time to do more experiments with the MATH table and help fixing potential issues. For the over-hat and over-tilde, they seem to display correctly in FontForge so my guess would be that you added variants/constructions for some specific code points but your test document uses other code points (there are several code points for "hat" and "tilde"...). I'm cc'ing Khaled Hosny, who might help to test the font as well.
