That's a pretty good list. Lacking only a few items its pretty close to my own personal wish list.
1: Yeah, actually "industry wide" its a little frustrating that a more universal and more functional standard hasn't been adopted and implemented isn't it!
2: Cant lie. Hate the child tracks. Have since inception.
3: Frequently requested. At
minimum, a selectable freq range for the mids. As is, very limiting. Long overdue.
4: Adjustable width mixer channel strips and more ability to reconfigure the order and arrangement. +1 X10.
5: Kind of fits with the above. Could just make the side bar collapse/disapear, that'd work fine.
6: Nice. Frosting, but nice.
7: I only disagree about the "only cosmetic" comment. An update/revamp of the built in metering, and metering options is another long overdue change IMO. Every serious competitor seems to have that, plus native true peak, LuFs, RMS, etc. data readily integrated for display and analysis, at least on the master bus.
Honestly, IMO the track meters could be reduced and simplified (Benefit, less space consumed) but the master metering needs a functional makeover/update desperately.
My (partial) critical additions to this list (yes, repeats of old requests!):
1: Gain trim knob for global gain control of channels/tracks. (similar to input trim on an analog mixer)
2: Normalization function improved/expanded to have selectable levels. Default normalization to 0
severely limits its utility IMO. Virtually useless for me. The ability to (for example) quickly and easily normalize to -6 (or -10, or -12.....) would however be a heavily used function for my needs.
3: Send return routing options. Please and thank you. Seems like a little thing, but it would be a big plus for me to be able to insert the return at for instance a submix pre-fader slot. (Or a "sub-master" bus. or whatever you might want to call it.)
I could go on....... there's some good ones.
