Diablotin is simply an excellent utility for those who "need" to manage their installed base of preference panes, startup items, fonts, contextual menu items and the like. Normal users can enable and disable items installed in their user accounts, and with an administrator account you can toggle those in the Library folder (and even the System folder if you like).

Diablotin is over two years old now, and the fact that it still works is testament to the quality of the programming. But then, if it works...why fix it. And really, I can't think of features I would need to see extra in this.

If you regularly try out new extensions (preference panes, contextual menu items, etc.) you need this. It's free. It's great. No doubt about it.
