Lets combine 'in-effects' with 'out-effects'.Lets create a notification that slide in from right and slide out to right.

$('#start').on('click',function(){
    $.amaran({
        'message'   :'My positioning example.',
        'position'  :'top right',
        'inEffect'  :'slideRight',
        'outEffect' :'slideRight'
    });
});
