RedQuits (or alternative) on Mac OS X 10.10

I have installed [RedQuits](http://www.carsten-mielke.com/redquits.html) on Mac OS X 10.10 (Yosemite). Unfortunately, it is not working *at all*. I have made sure that RedQuits has access to **System Preferences** > **Security & Privacy** > **Privacy** > **Accessibility**, but it seems to not work. Currently, the RedQuits website states it works with Mac OS X 10.6. **Does anybody know how to get RedQuits working with Yosemite, or of any alternatives that will cause the close button to quit an application?**
