UPMetroSkin VS Fluent-for-Steam

Sadly it's part of "Steam going Backwards" program that Steam retired https://developer.valvesoftware.com/wiki/Steam_Skins which https://github.com/redsigma/UPMetroSkin used to use Steam Skin with an OPTION you seek for to remove Big Picture Button from where you pointed out but now it's gone with lots of other good features as of the August "backwards" UI update.

You shouldve just google steam metro fix https://github.com/redsigma/UPMetroSkin and just simply change files
