@name           YouTube - No Gradient in Player
@namespace      Lu9
@version        1.0.0
@description    Remove/Repurpose the pointless annoying gradient overlay that takes way more space than it should on top of the player, makes the player slightly more like the default browser player, with a couple additional settings.
