The script used to build the pagination teasers in on the stage is not well documented (i.e. not documented at all) and also somehow not properly configurable on initialization. You will actually need to change the options directly in the script itself (which will force you to have multiple copies of the same script) or extend the object. In addition it has an ugly behavior when jumping back from the last to the first teaser.

"InnerFade" on the other hand works well, is well documented and easy configurable:
