Dark Skin for Crunchyroll
Source is on github: https://github.com/link07/Dark-Crunchyroll-Plugin . Everyone is welcome to contribute! This project is entirely based off of the Dark Youtube Plugin for Chrome. This addon aims to provide a quality dark theme for Crunchyroll.com. This is primarily because dark themes are easier on the eye when in a darker environment. It also leaves a button in the toolbar to quickly disable and re-enable the theme. If there are any un-themed pages, or other issues such as weird color choices, please report them!
