Launchpad in Lion gives you a nice graphical way to browse and load all your apps. However the default backgroundpicture or ‘backdrop’ as it’s called is a blurred version of your current user’s desktop picture.
There is a cheeky little way to change this by hitting ‘⌘ + ‘B’ on your keyboard whilst in Launchpad.
This shortcut will then toggle between blurred, normal and grayscale background versions of your current user’s desktop picture.
Nice little touch! 🙂
Sad News : For those of you that have run the Mac OS X 10.7.3 update, this has removed this feature. This feature is available throughout the beta releases of Mac OS X lion until the Mac OS X 10.7.2 update.
