Thanks, Awe. I appreciate that.
FWIW, my take on your take would be that
1 and 2 don't bother me, even if it would be more convenient to have them;
3 does bother me (as the world now knows);
4 would undoubtedly be useful but the R16's WC is by all accounts pretty darn good;
5 I can work around with the existing PFL and/or Mute switches;
6 is - as I understand it - a limitation of ADAT, so can the R16 be directly blamed for this? If I upgraded my ULN-2 to 2d, I know that the ADAT card in that won't work above 48KHz for the one way I would actually use it (just one more reason why 2d is of virtually no interest to me);
7, yes 100mm faders would be dreamy;
8 doesn't bother me;
9 yes, I'd probably develop a few of my own, as with all my gear. Nothing I own is perfect.
Apologies for the really terrible way I've formatted my reply
