User blog comment:Rupert Giles/Global Navigation January Update/@comment-5973717-20150130140357

Wikia rules say that this can't be installed wiki-wide, but you can put it in your global.js file: http://dev.wikia.com/wiki/WikiaNavBarHider

If you install this, the nav bar will stay at the top, waste less screen space, and adopt the color scheme of the page you're looking at. I'm going to update it when I have time. Enjoy, and if you like it, spread the word.
