Coming from 8.5.3, I'm looking for the very basic controls within the arrangement view like so :

Actually I'm missing the 2 essential ones, transpose and TIME SHIFT especially.
 
In X's I don't see them? How can I have them here and handy to quickly do all of the basic manipulation ?

I believe you find that in the Track Inspector.  Hit "I" and the inspector pops up.

Those two controls have been moved to the track inspector "P" in the illustration below from http://www.cakewalk.com/Documentation/default.aspx?Doc=SONAR%20X3&Lang=EN&Req=Inspectors.3.html#1220713

No longer deemed to be basic parameters...

wow Ok but the track inspector is a ''per track'' view, it's extremely restricting when you need a quick idea
of wich tracks are moved in time or in transposition, like so :

so is there a way to get this essential thing back? it's present in all daws, wether live or logic, quickly being able to
GLOBALLY view those parameters. Isn't there a user menu option to add it on the default strip?

actually why is something as obsolete as midi PAN present in the strip? sorry but this doesn't seem to make a lot 
of sense, as transposition and timeshift are much more used in general, and are now HIDEN instead of being quickly
overview-able and accessed
 
 
 

I use midi pan on every project.
im not why you think that's obsolete sir.
 
and to be honest, I don't use transposition and timeshift much at all.
 
I think what were seeing here is a difference in user work habits.
it gets us all. there are things ive brought up that people say "why would you use that all the time"
I think cakewalk took a look the big picture, they cany please everyone so they sent out serveys to ask questions to its users, they used those serveys, along with collected data and ofcourse the big one "common sense" to try and please as many folks as possible.
 
 
moving from 8.5 I will give you the best advise anyone can...
1-get used to keyboard shortcuts, there the fastest way to work.
2-use the inspector, at first it will seem like a pain in the bum, after awhile you will be amazed at how useful it is and how many features are packed inside of it.
3-grab a groove 3 video of sonar x3 explained. cake TV also has some good videos on site.

fair enough Charlie.
but still, why pan, volume, velocity, and NOT transpose and time?
 
It used to be that way and it made sense...
 
so why?

I think they found the majority of users were nt using it as much and that the inspector would be just as accessible.
I re edited my comment above, check it out. I left a link with videos. :)
 
youll get used to it, give it a chance Kewl  :) 

also there are options in the track preferences that may give you access to these control in your midi tracks.
use the track options in the track view, not the main options, youll see them.
they may let you customize your midi tracks a little bit.
