New features of Mac OS X Lion are slowly leaking out after the last Lion Developer Preview was released.



From TUAW:

The Lion app uninstaller works through Launchpad, Mac OS X's app launcher "home screen" layer. When Launchpad is displayed, a user can click and hold the mouse cursor on an app's icon; after a brief pause, all the app icons will begin jiggling. An X will appear in the upper left-hand corner of the icons, and clicking it will cause a dialog pop-up to appear asking the user, "Are you sure you want to delete the application?" Clicking Delete will move the app and any associated files to the Trash. Currently, this uninstall feature only works with apps purchased through the Mac App Store.
