THANK YOU. I am now coming back to this, after two years (sorry). Still face this issue. Have to open up my old .ttf files and combine them into a master? I’m trying to make a lighter font now, so want to delete some glyphs from all the weights (about 6 TTF files) all at the same time. It’ll be nice to know how to also change the INFO on all the fonts at the same time.
I saw the manual on Page 86, and it says something vague like “click the + icon on the bottom left”.

Which is the bottom left? See my screen with a TTF open…where’s the + icon to add this currently open file to a “Master”, and then add the other 5 TTFs to the same Master?
