Necessary Features:

1. Analysis and statistics per user, this is vital.
2. Integration of videos from any platform, not just YouTube/Vimeo, some of us use other options.
3. Personalization of certificates.
4. Create courses or lessons from PDFs or PPTs
5. Community: It's essential, even if it's just one comment box per course. Ideally, it would be in each lesson and even a group feed, but one comment box per course would be essential to start.

I completed a course with a test user. When viewing the course statistics, the progress for all blocks is at 100%, but the test user provided feedback on the blocks, and it isn't reflected. Additionally, in "user details," it shows that the test user "hasn't started the course", and finally, in the assignment results, it indicates that no students have submitted responses.
