this AdOn is hardly usable!

Absolutely no setting options in the app, nothing at all. youtube movie windows are enlarged, but I don't want that because I want to decide for myself how big the window is. There is no possibility to set the HD in the app, no you have to do that in the video. Too many inconsistencies, therefore not usable, uninstalled again! Because I decide which settings I want to have and not the one who offers the AdOn, something like this is not possible!
And as I see, no update for 3 months, that explains a lot!
