Displays a colored icon when reviews and lessons are ready on WaniKaniGet a colored notification icon in Chrome when you have radicals, kanji, or vocabulary to review or learn in WaniKani. This extension adds a small, non-intrusive icon to the right of the address bar which turns red when reviews are ready and orange when lessons are available. A minimum number of reviews can also be set before the icon turns red.
