Can't hide the Recording button in the steam overlay taskbar

[Tomandandy]

In the settings, there is an option to enable/disable the individual buttons that show up when opening the steam overlay while playing a game. That feature is very handy for keeping the taskbar neat and tidy.
However, it seems when Valve added the new "Recording" tab, they forgot to add the option to also disable that button via the settings. Please add that function as well, thanks.
