I didn't assume this extension will amass this huge an audience (>400K), I hope you understand how much time and energy it takes to maintain something like this where YouTube is actively trying to shut-out everything for such a large userbase while trying to work >80 hours on your own thing. If you are still not satisfied with the decision, you're happy to downgrade the version to 1.3 as I won't take anything down, it just won't be maintained. I think that is fair.

It's currently priced at 5.99$ as a one-time lifetime license fee with guaranteed non-stop support for at least 12 months. That's 167.88$ for YouTube Premium, is that a deal-breaker for you?

Thank you for the security advice, I will do that.
