Gallery index/search: Improves appearance/layout, parses and cleans up titles. Can hide/fade galleries by tag (requires flagging perk). Can resort gallery thumbs which is useful when hiding. Gallery view: Can adjust thumb sizes to make neat rows (requires large thumb perk). General: Option for grey color scheme by rewriting css (might have a few issues). Settings panel pops out on the left on mouseover on pages where it works.
Favorites tick box
When you go to the personal favorites page while using this script, the tick boxes at the bottom of the listed titles doesn't work. Also, the highlighting function doesn't work with the "Popular right now" panel. Other than that couldn't find anything. Awesome job.
