Feature Request: 'Filter' custom parameter for masters



I think it’d be useful to be able to give masters the ‘Filter’ custom parameter for use with exporting variable fonts.

For example I currently use this script to export my variable fonts with all components decomposed (to fix the spacing issues on mac) but having it as a filter would be much simpler workflow-wise.


I’m thinking about a place where to put variable font settings like this. Masters are not quite the right place, think.
