Well, it's finally happened, Valve changed a thing. There's a new Storage Manager feature being added to steam, which has affected libraryfolders.vdf formatting. This release resolves the most apparent issue from this change, identified in #37 (thanks @sharkusmanch).
Game Pipe will now recognize libraries added via Steam, in both the new and old format, however the option to add and remove steam libraries is now disabled to prevent errors within the new format of libraryfolders.vdf, attempting these actions will give a message that leads you to the library manager.
