Matrix view and staff view I have never even opened.  But like so many others, I probably use 40-50% of what Sonar actually offers.  I just use what I need to make rock music and move on.

But I'll play along...I never use the Console View.

And here I was thinking I was the only one:)

No joke. I have yet to use the console view. I just assumed it was already gone.

I use the CV often. I use the TV as well. But what I wonder about is do we really need all that audio crap?

Hmmm, all of the updates since Jan 2016. LandR was so not wanted that I backed out of that update and stayed there.

all that audio crap?

be more specific?

I guess all you audio guys never think about MIDI. 

some (most?) of us use both midi and audio

Never used punch in or out. And the theme editor is redundant for me, I can't believe how good SPLAT looks on my big monitor just as it is. 

Ditto for Punch In/Out.  It's a holdover from tape, and has been deleted from my Control Bar. Now I start the recording a couple of bars early, get the feel, play what's needed, and Slip Edit the extra recorded time.
 
Then again, since the developers are busy adding and improving, REMOVING anything seems a waste of time.  After 14(ish) years with Cakewalk, one of their best selling points is workflow versatility.  I can use it for strictly electronic music, record live like tape, or any point between.

Pretty much anything having to do with audio loops.
