TwentyTwo is a Mac OS X application which brings 22tracks to the desktop without using a browser.
Why is that good?
- No more 'trying to find in which tab is 22tracks running'..
- Media keys support! (Yeah, those with ▶ ❚❚ on them.)
- Stops on suspend.
Yes, this is available here: https://github.com/marcw/twentytwo/raw/master/dist/TwentyTwo.dmg
