Just a small hiccough I noticed:
When (and after) two Font Infos are open, it seems I cannot save the file (getting this clicking system sound that says “doesn’t work”).
The problem remains until I re-open the font. Then saving while in the Font Info is possible again.
Just click on the main window. Then it will save normally. I’ll fix it.
Same with Export, I think. Would be good to export when info/features are open, I find I’m endlessly closing and reopening it to jiggle with the features.
It was getting on my nerves, too. And now, when I try to fix it, it works as expected. grr. These bugs know that you looking for them and go into hiding.
