Hi there,
Thanks!
1. We feel the theme itself is already perfect for page builders due to its simplicity, so we likely won’t add any page builder specific features.
2. We’ll tighten integration a bit, but we’re working on a separate block plugin which will extend that integration (and work with any theme).
3. Yes, we’re working on a plugin to integrate GP with AMP. You can use the current version here: https://github.com/tomusborne/amp-for-generatepress
Once it’s ready, we’ll release it as a plugin on WordPress.org.
4. We’ll continue to refine the theme/GP Premium, improving the overall UX. We also want to add deeper WooCommerce integration, and possibly create a couple more standalone plugins to integrate with other well-known plugins.
As always, speed and performance is something we’ll be looking to improve as well.
