I work with several VST instruments that uses keyswitches and I work constantly on PRV.
The problem is that in PRV, visually, the range of the instrument's notes are mixed with the range of keyswitches, like the image below.
I wonder if there may be some visual indication within PRV to SEPARATE the range of notes and range of keyswtiches.
Something that would also help a lot is if it were possible to visually indicate what each note on keyswitch is (as shown in the picture, for example, the note D#1 activates "Legato").
 

I think the closest you can get is to make a drum map for each instrument.

I would love to see Sonar work with NKS so Kontakt key switches and key zones would be automatically coloured in the PRV, but I doubt that will happen anytime soon.

Alternatively, couldn't you just make a separate midi track containing only the midi for the keyswitches, and change the color of the midi notes in that track to differentiate between them in the PRV?

^^ This.
 
I have about 30 or so drum maps set  up in my mega orchestral template all for the different keyswitches relating to EWQLSO Platinum.
 
It took a while to set them all up but it was well worth the effort.

Making a custom drum map for each Kontakt instrument would be the most elegant solution, because it lets you name the keyswitch functions. But it's also a lot of work, especially if you use many sampled instruments, each of which will have its own set of keyswitches. It can be further complicated by instruments that let you redefine keyswitch assignments. In multi-instrument bundles (e.g. orchestral packages) you'll likely have different keyswitch values for each instrument, possibly requiring separate maps for each if there's any overlap.
 
I much prefer JesDes' approach, which is to put keyswitch events in their own track and give them a helpful color scheme. This works just fine as long as you have a limited number of keyswitches, but gets progressively more clumsy as you pile on more of them. Fortunately, most people are only using 2-4 keyswitches for a given instrument. It works for me.

There is yet another approach: instrument definition files. You can create one in MIDI/Instruments/Define... preferences. You will need "Note Names" section. There is export/import functionality and files are text ini files, easy to edit. You can then apply particular mapping right clicking on piano roll.
 
Advantage: simple to define, simple to apply on whatever track without changing the routing.
Disadvantages: PRV does not remember this setting and there is no "keys" graphics.

And when you press a key on the keyboard, it isn't highlighted in the note pane.
 
I just wish Cakewalk would just let us right click on the note pane and name the notes, let us color them individually, have the colors applied to notes in the PRV, and allow us to save a reload these "note maps" at will.

Cakewalk has done such an awesome job in the past couple of years on the Audio side of Sonar!
 
I think it would be cool to see some Midi love. Both in features/fixes and in training!
 
We love Midi!!

JesDes proposes the easiest solution using Sonar as it is now.   With the key switches in a different track, but sending the midi data to the same VSI as the main track, you can keep up with distinctions, you can transpose the main track, etc etc.    If they'd only improve the controller pane in PRV, this would be a feature instead of an annoyance. 
 
The instrument list is another place that great help would be possible, but no developer at CW seems to get interested in such things.    MIDI!!
