Good plugin, with active developer

EDIT: the bugs I mentioned below have since been fixed by its awesome, attentive developer. Much to the delight of everyone involved with the relevant project. Rating updated accordingly.

Good plug-in, all-in-all. Usability-wise, there’s a lot of room for improvement. Setting up/configuring the new fields works nicely, but the result that the content moderators will be using is a little weird: if the field is set to be REQUIRED, it’ll see it as empty even when there’s already a video selected. It only checks the “search video”-field value. So every time you edit a post with this field in it, you have to put some letters in there in order to be allowed to press SAVE.
