I have tried this slider but it doesn't suite my needs due to it's lack of certain customizations and little things like the thumbnails not working.
I have tried this slide on two different sites both with no other plugins activated that could cause conflicts and on both the thumbnail images do not show up. Also, if set to a white background there is no way to alter the background of the thumbnail navigation arrows. If the background is white the background of the nav should be white as well, at least in my opinion.
It would be nice if there was a resize option for images as well on upload so that they fit proportionally into the set width/height of the gallery.
As a developer I would also like to have easy access to the CSS to modify layout options.
