Google rolled out an updated YouTube layout a couple of days back. The new design makes YouTube more consistent with other Google properties. While the reaction to the new design has been mixed, one aspect of the new YouTube has drawn almost universal ire. YouTube is now left-aligned, much like Google Plus. On high-resolution displays this results in loads of white space on the right of the screen, and makes the YouTube surfing experience extremely jarring.
Fortunately, it’s rather simple to fix this design issue. All you need to do is install the “Youtube Center Aligned” user script. The script works on Firefox, Chrome, and Opera. You can get the installation instructions for Firefox and Opera at UserScripts.com. To install in Chrome, simply download the userscript, open the extensions manager (Tools –> Extensions), and drag-and-drop the downloaded script onto Chrome. Alternatively you can install the Tampermonkey extension for Chrome, and then install the userscript.
Even with this script, there is a lot of wastage of screen real-estate. My favorite YouTube userscript is Unique Youtube Skin, which automatically resizes the video to make full use of your screen.
