I was just working on making some updates to the backend WordPress code for the Principia Pilot website (http://principiapilot.org/) and noticed widows in some of the stories.
Widows are the typographic term for a single word on a line at the end of a paragraph. I thought about the solution to this problem (basically add a non-breaking space before the last word of a paragraph) and then realized probably someone had written a plugin to do exactly this.
I tried two different plugins and like this one the best because it doesn’t overwrite the rest of the excellent WordPress typographic niceties like converting straight quotes to curly quotes:
