FollowDex от Xefir

MangaDex miss a visual indication for mangas you have already in your library when you browse or search for mangas.
This extension will fix that by applying a red background to these.

/!\ KNOWN ISSUE
Because the list is loaded the first time you load the website, you must reload the page when :
- You add or remove a manga from your library
- You log or unlog from MangaDex
