+Glyphs.app plugin for exporting a variable font with an automated KERN axis (for fading out kerning). 
+
+After installation and an app restart, choose _File > Export,_ pick the _VAR with KERN_ option in the export dialog, choose an axis tag (`KERN` recommended), and an axis name (default ‘Kerning’), click Continue and choose a destination in the upcoming Save dialog. All Variable Font Settings in _File > Font Info > Exports_ will be exported with an additional kerning axis with a range of 0 (no kerning) to 100 (fully applied kerning).
