I'm pretty sure Mac has seen this.. and knows how awesome it is to have that ability when mixing.

I have found the mixer screen to be less and less useful myself, if only there were a way to quickly (and intuitively) get to the AUX and MASTER FX area without the mixer. To be honest I like the dials for the AUX send on the mixer, with the ability to see the same for related tracks, and a few other unique views there in the mixer, so it is handy at times. I don't think it's 'completely unnecessary', but I do see what you are getting at. A lot can be done in one screen. It has to be done carefully though, or that one screen can be quite a challenge to new users.

I do not work here, but the benefits are still awesome
