The latest build of Mac OS X Lion introduces an iOS-like method of removing applications installed via the Mac App Store. Within the new Launchpad application, users can click and hold on an app’s icon to start the ‘jiggling’ – just like in iOS – and an ‘X’ button appears in the corner of each icon which users can click to uninstall applications.
Don’t worry about deleting applications accidentally, however; just like iOS, users will be greeted with a message that asks them whether they’re sure they wish to delete the application. Clicking delete will move the application, and any files associated with it, to the Trash.
This feature currently only works with applications purchased from the Mac App Store, but I’m hoping it works with any application installed on your Mac when Lion is finally released.
