If you try to go to Help:Widget, there is no page and Help:Widgets is a useless redirect (feel free to complain via Special:Contact/feedback). So, I'm pretty sure widgets, while they may work for now, are unsupported. They were a feature of the previous Monaco skin.

As for the Video Wikia question, that definitely sounds like a Special:Contact/feedback question. However, as I said, Special:Video is not a wiki-specific collection, so it isn't cluttering your collection, because it is not your collection. I consider it a bug that the page title is "Videos on this wiki". You could send a message to Special:Contact/bug in that regard.
