I am a big fan of user-scripts and Wikipedia. However the Wikipedia design has always struck me as a bit unwieldy sort of when the design becomes too flexible for it’s own good. I found myself always resizing the window whenever viewing a Wikipedia article so I wrote this tiny user-script that sets text-width to 450 pixels and changes the type to Georgia. I am gonna try to do a black background save-the-eyes-script alternative soon as well.
You can find the script here
