option to use mix 1 to 10 as group faders and mix down to the main mix
Yes please!!
I miss this! would be a very useful function!
I am very surprised that it was not implemented natively.
I bought the QU-16 two weeks ago, so far it is the only serious flaw I found.
yes please, competition has it 
Just got mine. This is a must fix!!!
Official statement from an A&H “product manager” as answer to a pre-sales ticket:
"Right now the big request is USB windows support.
There are no sub-groups in QU-16.
Channel names inside the QU-16 is not high priority
If you cannot work with the great QU-16 feature set as it is at the moment then I suggest you choose something else."
That sounds like groups aren’t going to be part of the Qu-16.
There should be a way in software to just send the Mix buses back to the LR main mix. Please.
