Instead of this, you should focus on improving the filtering of themes, which is almost useless as it is now. Nobody searches themes by "Custom Logo", "Featured Images", "Microformats", "Sticky Post" or "Threaded Comments". People look for themes compatible with WPML, WooCommerce or Elementor. Or having a Masonry layout, or Google Fonts support. Or having a specific number of stars or active installs.
