As far as I know deleting "interface_namechar.icfg" will reset your game interface like the placement of action bars etc. Maybe this should be mentioned explicitly?
Yes, it would reset the interface to the default. All the changed options will then be cancelled and will have to be done again.
You are right, I will specify it.
