iTunes with Multi-Touch

Ello,

As a fellow MacBook Pro user, I'm waiting to see if the new MacBook Pro's will feature multi-touch. Regardless of when they are released, I began thinking about the use of multi-touch in other applications aside from the ones demoed at MWSF.

iTunes is the application I use most on my Mac, since it consists of all my music and film collection (now I've began re-ripping everything as .mp4 with H.264).

Things like volume control, changing tracks etc would be so much more easier to do (when I think like this, I realise how lazy humanity has become..) if you just swipe the trackpad rather than having to slide your finger and navigate to the controls.

Is this a possibility from a 3rd party addon or even something already there? I've tried to keep up-to-date with it all, but sometimes it is easier posting a new thread than skimming through several others.

Discuss!
