Almost perfect, downloads YT vids as expected. Paywall for HQ vids but that is stated clearly. Problem is, when EYVDE is enabled, opening a video's page leaves that video not playing, waiting to be started. Ordinarily when opening a video's page, the video starts playing immediately. No other YT specific app changes YT's behavior this way. This should be examined by the developer. Another negative is the developer only accepts messages from paying customers. Such behavior is just dumb. I won't pay for a program if I see it has a problem, but cannot tell the developer because he chooses not to listen.
