It’s not difficult for us to handle this through a permission in the settings which I would rather setup then having y’all copy some UI CSS. We can probably finish this around the end of the month.
If you setup a CSS file to hide the Themeco Templates you could use something similar to this code which would add styles to the Cornerstone App.
add_action('cornerstone_app_enqueue_scripts', function() {
// wp_register_style( 'cs-hide-themeco-templates', '...' );
// wp_enqueue_style('cs-hide-themeco-templates');
});
You can also disable max globally through this filter
add_filter("cs_max_enabled", '__return_false');
Have a great weekend.
