Forked this for personal use and added/changed some things here and there:

• custom red Danbooru-based theme
• added rating visibility control for users to toggle safe/explicit content on or off (if they have permission to see it)
• hide side-wide list of tags and, if enabled, popular tags from anonymous users
• hide list of pools to anonymous users
• added keyboard controls to /post/list and /view
• changed home extension to allow for configurable logo and logo link
• changed index.php's site title behavior to also be configurable with a logo and custom logo link
• changed Autocomplete extension to load current theme's css last (currently dirty since it results in theme's stylesheet being loaded twice)
• various other fixes
