“Use Live on two monitors. See the Session and Arrangement at the same time. Work with a clip and its devices simultaneously for better control of Session automation.
Live takes advantage of multiple monitors to show you more at once. Use your second monitor to keep the mixer visible at all times. Dedicate a whole monitor to detailed MIDI clip editing or the Arrangement. Or view your recorded Session automation while tweaking devices.”
Who waited for this… I DID! YEAH! 🙂
@Ableton: I love it. Thanks a lot!

Having two screens up is so crucial.
yes, very soon now… I hope
It sounds like a cool idea but it won’t work for visually-impared folks like me. I’m glad it works for you.
Well, it didn’t work out for me. With minimizing my sound library I minimized my desktop, too. So, I’m back to one screen. Helps me to focus.
