Tool for using Steam-Input controller rebinding at a system level alongside a global overlay

GlosSI Overlay

GlosSI provides it’s own overlay in addition to that of Steam.

Simply double press your assigned Steam overlay key(s) or the Steam/Guide button to bring it up.
From here you can take a peek at the log and change various settings.
