It's an app I developed to mimic ALT-TAB behaviour.

I am a proud Desire Z owner and have to say the Vision is amazing with its keyboard. One thing I still hate about day to day tasks is switching between Google Talk and MSN apps. I hate reaching up to the notification bar from the keyboard.
So I wrote an app to solve this problem. I call it QuickSwitch.
By taking advantage of the quick keys on the keyboard, I wrote an app that basically launches other apps. It's configurable which apps you want favourit-ed and how many running apps to show. I also made it mimic alt-tab function by pressing Quick key 1 and comma. This would switch back and forth between apps very quickly.
If you like QuickSwitch, You can send me a donation to my Paypal http://bit.ly/quickswitch-donate-paypal or through the Android Market and search for "QuickSwitch (Donate Only)". The donate version does not add any functionality.
