Hello,
I’m slowly becoming an enthusiast user of the “filename” custom parameter (mostly to add specific suffixes to instances, like FontNameBoldItalic _App .otf). For a complex project, with a lot of instances, I’m finding quite tedious to rename them one by one (especially since the family name changed during the lenght of the project): now, I know that I could easily do it with finder, but I would like to keep everything within glyphs for added flexibility. Would you consider a custom parameter that adds the provided suffix between the FontName and the export extension?
