Removing the LivePreview and Share Buttons? Is there a way to deactivate this functionality? We dont want our clients to use it just yet.

I could delete them with my Module's js, but it is triggered after the site is build and the "popping" away of the buttons is not really pretty.
If you add a blank or invalid template path in your Section's settings (Settings > Sections > Edit Section) then both live preview and the share button will be disabled.
