Scripting ability greatly improves the UI. If you want to look at pictures of cats, it's nice to have thumbnails and the ability for the image to expand when you click on it. Me and a few billion persons find it more comfortable that way and only one anus in /prog/ thinks it would be better to open the image in a new tab. In fact he'd rather have a text gallery in gopher and ftp links to download the images. Documents with pictures? Many pictures? Heresy.
