Yea, that's a bit confusing and I should probably do something about it. If you install more plug-ins (there is currently only conboy-midgard) it will make more sense, because then you can choose which plug-ins should be activated. If, however, you only have the default plug-in (which is the XML backend) it dosn't make sens to deactivate it. If you deactivate it, Conboy is simply useless I should probably implement, that if there is only one plug-in, then the selection should not be shown at all. I'll see what I can do.
