Interface isn't as clean as more recent plugins, and I needed about 40 lines of custom CSS to theme it to my site, but it does EXACTLY what I needed. I now have a way to insert a clean YouTube channel listing on a site that plays in a lightbox without leaving the page. Has some options for filtering results based on tags that I haven't tried yet, but overall the base functionality is very good. I'm using Elementor Pro, so adding it was just drag-and-drop from the widget list. No mixed-content problems, either.
