My window manager of choice is "Enlightenment 17":http://enlightenment.org/, which has been in development for at least the past seven years, when I started using it. While generally awesome, e17 has never had a stable release, which means that features sometimes break. Last November, my theme of choice, "Milky's":http://exchange.enlightenment.org/theme/show/1594, stopped displaying the titlebar properly. Since the last release of the theme was from early 2010, I finally decided to learn about the e17 theming system and fix the problem.
