I’ve been using a premium schema plugin and need to replace it, upon browsing options I notice your AMP plugin might need a special support as can be seen here:
Where they support Automattic AMP plugin.
Upon testing some of the free plugins, none of them fit my needs and I would have to go for one of the paid options and thought I should ask you first, as your stuff is fantastic and be using schema plugin special built for your themes and plugins would be the best option.
I also use Yost premium and it seems they are not going to add a full-blown schema anytime soon.
If you make a schema plugin, you would have to keep this plugin compatible with some of the major SEO plugins out there.
Also, regarding all your add-on plugins, could you make them all under one link in the admin, just taking up too much space on the menubar.
