No Scroll Arrows

This Plug in would be great.
I installed it.
I added the links for youtube
I looked at all the settings and there is nothing about adding more than 4 thumbnails to choose form.

I have 15 videos that I would like to add to the gallery but when I do there are no arrows or buttons to go to the next page or additional videos.

I’ve uninstalled this plug in and I’m going to recommend that people do not install it on their site for this reason.

If you’re the developer, why would you release a unfinished product?
especially one with such an obvious problem.
