A fork/expansion of the user script "Wikipedia 2 Wikiwand" <https://greasyfork.org/zh-TW/scripts/13400-wikipedia-2-wikiwand> to make the script applicable to most languages of Wikipedia (hopefully). Trying to do the similar thing to official browser addon/extentions of Wikiwand, an elegant and nicer frontend of Wikipedia.
Works correctly with the desktop version of Wikipedia, but not the mobile one. Use Pigfoot’s version instead if you also need it to work on iPhone as well: https://gist.github.com/pigfoot/e43748805cf802774c2fd3e1aee137d4
