Wikia's stupid "Trending Fandom Articles" side panel.
The PLA's Wiki will be perfect the day wikia.com removes that fucking ugly GIANT piece of useless trash that is the "Trending Fandom Articles" side panel!
Wikia doesnt alow users to remove it. Supposedly, it's a "In-testing" beta feature... Lets hope they decide to remove it completely!
The only way I found to hide it (exept adblock) is to zoom the browser 110%.
