Is it possible to have a slight fade to the .slideUp & .slideDown so it slides upwards with a fade?
options.trickerPanel.slideUp(function() {
$(this).html(value).slideDown();
Here is the full code for example http://jsfiddle.net/LtpHv/1/
Try this
$(this).html(value).css('opacity', 0)
.slideDown('slow')
.animate(
{ opacity: 1 },
{ queue: false, duration: 'slow' }
);
