API methods :
1) toggleInfo ()
onInitComplete  I use : $('div.jb-bb-btn-show-info').trigger('click');
2) getJbBtnStatus (): Object
{ShowInfo: true / false,
ShowList: true / false,
autoPlay: true / false,
audioPlaying: true / false,
fullScreen: true / false}
to get the status of  jb-bb-btn-???
For now I use  the "title" attribute, using the plug-in 'tipped.js,' to display  a clear and detailed information about  button's action depending its status.
3) if config.backbuttonposition === "OVERLAY" do not hide it when Hide Information
4) an API method to hide all objects except image
I do it this way :
        $('body').on({
            mouseenter: function() {
                $visible_collection.css({'visibility':'visible', 'opacity':1});
            },
            mouseleave: function() {
                $visible_collection.css({'visibility':'hidden', 'opacity':0});
            }
        });
