I've been using the extension for a long time, and in my opinion, it has only one drawback — the background. It's really unfortunate and limiting that we can't use anything other than an image or a GIF for the background. Since GIFs aren't as high-quality as videos, I believe this is a major shortcoming. If they added the ability to set a video as the background — even something simple like allowing an MP4 — I would give this extension more than 5 stars. I truly hope the developers take my words seriously, because it saddens me to see such potential not being fully utilized.
