I hear CA and I have just learned to use FOLDERs and expand or contract as needed. Yes, I can't see a lot at the same time but this allows me to have a very wide CONSOLE view in order to see a lot of tracks in the mixer metaphor. Thank goodness for the channel coloring ability, this has made finding tracks in console view somewhat easier. I don't use PRO CHANNEL at all so the limit in height isn't an issue except the fact that the number of sends is limited and I can't stand having to arrow up and down to mix with the sends.
I prefer the CONSOLE view to the track view for mixing anyway. If anything, I have been contemplating getting one of those ultra wide monitors for CONSOLE view only usage.
You did give me a thought though, how about having a FOLDER type view in CONSOLE mode wherein the tracks that are contained in your FOLDERs are collapsed in CONSOLE view as well with the ability to expand or contract folders in CONSOLE view as well. This state of FOLDERS would persist between views (with my track record, this feature probably already exists and I just don't know about it). :-)
BFD3 does something like this in their built in MINI MIXER and I find very productive given the small size of the VSTi window in SONAR.
