Beta client update added plenty of references including controller bindings, new UI strings such as quick access menu, system settings (airplane mode, wifi, bluetooth) and a power menu. https://t.co/BwDWjWWb06
This update also added a "quick access menu" and a "power menu"

It's named "SteamPal" (NeptuneName) and it has a "SteamPal Games" (GameList_View_NeptuneGames)
There's also something called "Callisto Developer Program"
