Hello guys,
The settings dialog for this extension has two switcher (I don't know how they are actually called). I wanted to know what the second does, as toggling didn't change anything.
I started digging and quickly found the prefs.js and there I found out that the second switcher does nothing, when the first is enabled.
I suggest, that the second switcher is deactivated (= one cannot toggle the state) when the first one is enabled. I think this is then more intuitive and does not confuse people :D
