Global Font Control
You need to add a list of forms, screens, etc. in Company Preferences with a drop-down field next to each of them so that your users can select the Google font they want used for that particular form or application.
You have had suggestions int he past for a font selection option for emails. This option should be global for anything the client comes into visual contact with so that we can tie our branding together and not have it looked like it was patched together.
