How can I hide thumbnails or other elements in full screen mode?

When the slider is in full screen mode it gets a custom CSS class called n2-ss-in-fullscreen, which you can use to hide controls or layers when the slider is in fullscreen mode, or do any other full screen only action.

For instance, if you want to hide the thumbnails, you can use this code, which you can put into your slider's HTML control or to your theme's CSS file without the style tags.

<style type="text/css">
.n2-ss-in-fullscreen .nextend-thumbnail {
	display: none !important;
}
</style>
