Android 2.2 enabled apps to be moved to SD card, which is great, but with the annoying part of having to scroll through all your installed apps seeing which ones can be moved.
SDMove lists all your apps and colour codes them to whether or not they can be moved with a legend explaining what each colour means, such as "The program prefers being on external storage, and is already there", or "The developer has requested the app be prevented from being moved to external storage". Clicking the name of an app will bring up the screen where you can move it to the SD storage.
Very helpful app for when you first upgrade to Android 2.2 and have a lot of apps installed. Saves time going through them one by one just to see if they can be moved, whereas with this app every app is summarised in one screen.
