Koush releases open source ClockworkMod Superuser app
If you have never rooted an Android device, a superuser app is what lets you to control what apps are allowed to have root level access, and when that access can occur. There are already a couple of superuser apps available, but when Koush releases one, the community takes notice.
In addition to the basic functionality that you’d assume from a superuser app, ClockworkMod Superuser has multiuser support, logging and per app logging, PIN protection, request timeouts, customizable notifications, ability to handle concurrent superuser requests, support for x86 and ARM, and a pretty UI. Of course, it is also free and open source. Not a bad deal.
If you want to give the app a shot, just head to the source.
