Ha Ha ,, I'm going to try it for the first time this weekend so don't delete it yet!  

Great! It is a feature unique amongst DAW's and deserves more users. Once you get it set up how you like it and understand it's quirks it is awesome . A bit like all of Sonar really:) Good luck with it Johnny.

I'd say ACT... I could happily watch that go.

I don't need rewind/rtz. Forward Only, I say.

The Auto R default ON feature! When loop recording, all tracks recorded come in with the R "on" and not only do you have to turn them all off... It can not be turned off (unchecked) even if the R is off...

SONARPLT.exe ... probably without this executable, Platinum could work under Linux. But that very small component of Sonar (27Mb out of 1GB minimal installation) fail, is it really required?

Halo Freq
Staff view, score view???? Really...not if you read music

Exactt.
Means that I never use it and notation isn´t a feature  I woukd ever need .
 
Welcome here.

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. 

Since the thread is more serious then I thought...
Theme editor - I can imaging I modify 1-2 "bad" button colors, but that was possible before. Good design requires pro. grade education which I do not have. If size and position of elements could be modified, that could be "pure man" solution to adopt Sonar for small monitors. But that is not possible.
Score view - not comparable with specialized editors, even free. And I do not need it "build-in", when I need it.
 

nevermind...

What platinum feature do you guys think we could actually do without?  For me, Matrix...

An impossible question. Unless by "we" you mean you and everyone who has exactly the same workflow as you.
 
SONAR is so feature-rich that most - no, ALL - of us utilize only a subset of its capabilities. Anyone's personal list of unused features would be quite long, no two users' lists would be the same, and nobody's list would be complete because you can't include features you don't know about. 
 
But I'll play along...I never use the Console View.
