If you have a myriad of launchers installed on your phone, this is the app for you! I have LauncherPro installed on my phone and I like to switch back and forth from HTC Sense. This app makes it faster and easier to switch. Just open up this app, and click "launch" on which launcher you want to use. Just like that, you're on a different launcher. With this app, you can set which launcher you want to be set as the default. You just open up the app and click "set default" on the one you want to be the default. This is a great app for those with lots of launchers installed and I highly recommend this app!
