I have MagicButton installed and I find it great but there are times when I'm using my PDA with one hand and I want to switch between apps. I have one of the hardware buttons mapped to "application switch" using ButtonMax but it's tedious going through all the apps you don't want (including the today screen). I'm looking for something that will be activated with a hardware button and then you can select the app you want (from those currently running) with the D pad. I suppose something similar to ALT-Tab on Windows.
