Would be amazing if you could go into "producer mode" and hide the clips in session view. Just like you can show/hide I-O, send/return, mixer, track delay and crossfader!
This would make room for more faders (or bigger faders), piano roll etc. (depending on monitor size).

You pretty much can, although it's not a single button. If you hover at the top of the faders there's a handle you can drag up to make them quite a bit bigger, and likewise you can do the same for clips (piano roll or waveform) by hovering at the top of the detail view and dragging the handle all the way up. Hope that helps.
