We are alive and I understand where the question is coming from but any membership or single purchase is not promising or saying that a certain number of templates will be released. 150 templates and 70+ mods are included in membership as of now including support for all of these and a stable framework that as far as I know did not give you headache. I say that is ok price for dev membership.
Again , I know exactly what you mean and what I just said should not be taken any other way. We are pushing hard on WP now https://themezly.com/
and in next few weeks many changes will be coming to both YJ and Themezly. I would love to give you all 50 demos that we have on WP for Joomla but we must find a best way possible to convert those. Joomla 4 is coming soon and that is headache on its on. So yes we are alive , we want to give you more but we need to find a best way possible. I hope you understand.
