Is there an App..Task Switcher?

[BPFerrari1]

I'm looking for an option or app available to better switch from App to App. Today I was listening to Music, using Google Talk, and browsing on Dolphin and it was annoying to keep going back to the Home Screen and then the App Panel and find the app (I don't have the app shortcuts of these on my home screens). I thought it would be nicer that I just press the Home button, I can get a pop-up of my last few apps or running apps and just a Home option to go back to the main screen if I wish...This way it's just easier for any apps I may using at once.
