@cabralpedrofccn Thanks so much for sharing your thoughts 
it’s great to hear from someone with hands-on experience in both Moodle and Open edX (as well as actively running a MOOC platform). Feedback like yours helps us think more clearly about how to design features that actually make a difference.
With this in mind, could you check out this post: What’s on Your Open edX Wishlist? I think with your background you’ll definitely be able to provide valuable thoughts to this post.
