Pre fader listen isn’t actually pre fader (post inserts)! It’s before all inserts and before the channel pre-section (gain, LC, HC in the rack).
I want to use the listen feature of control room (which is basically a solo that can be switched between pre- and post fader, amongst other things) in pre fader mode in order to check my channel signal with everything but the fader position taken into account.

Same applies to pre-fader metering. I would like that to be (at least optionally) post inserts, right before the fader.
