Thanks for getting back and updating. Added a more clear note to the addon description now. I just tested around a bit, can't get members-only videos to appear in the sidebar. But I just released version 3.1 which should now also include the sidebar, see changelog.

previous reply: I never intended to include videos in the sidebar, as I solely use theater mode (and tbh. don't even get the point of why one would watch a video not being in the CENTER of your screen)
