Customizing Filmstrip Nav Bar

Hello, love the plugin but still tryin to customize it, layout wise.

i’m using the filmstrip navigation above my slideshow. what file do i look into editing, in order to change the height of the filmstrip navbar area?

my images are sized as i want them, but there is still lots of white space beneath them, and the left and right arrows are displaying lower than the images themselves.

i think the div that holds them is set to a specific pixel size and i want to diminish it.

any help is greatly appreciated, thanks!
