CocoaMondo Kit 1.1
I looked high and low for a switch interface similar to the Time Machine switch. The iPhone uses this style of interface all the time with the UISwitch. Since I couldn’t find an implementation, I bit the bullet, created one and added it to CocoaMondo Kit 1.1.

Please don’t abuse this control and replace all your checkboxes with switches. Use common sense. A good guildine is to use a switch for a desktop application when the state of the switch has fare reaching implications. For example: The switch disables or enables the core functionality of the application.

If switches are used sparingly then the user will hopefully pay closer attention when enabling or disabling them.
Kode on!
