I was wondering, is there a way to test anchor positioning for baseglyph-mark combinations that don't exist pre-composed in the font? For instance if I wanted to put an ogonek anchor on B without having Bogonek in the font.
Thanks for your help.
Just have a ogonekcomb with an _ogonek anchor and an ogonek anchor in the B. Then use the 'Show mark Preview' plugin from the plugin manager.
