As John Barron suggested, I report an issue here, which I reported earlier on facebook. I searched for this particular issue on the forum but couldn’t find anything.
I slightly altered some fonts to display lining numerals instead of oldstyle numerals per default, they got renamed and I’d like to relink them, but I don’t know which is which because the fields are to small to show me all the info I need (Especially Missing Family but Replacement Family isn’t great either). I also can’t resize the columns.
This is how the fonts are named, and I guess it’s very well possible to have longer font names, which differ only at the very end (or in the middle or whatever). So it is crucial, to be able to see the entire font name.
