The behavior of controller pane is a huge pain and serious problem that should be fixed already.
Controller pane displays every messages in selected track(s) which makes the controller pane a huge mess.
It requires a lot of time to clean them up.
Even worse, after cleaning up unwanted controller lanes, all the messages come back again everytime opening PRV or track focus gets changed.
 
Controller pane should
1. remember which controller lanes were open and closed per track.
2. not refresh the view when track focus gets changed or opening PRV.
3. be scrollerable multiple lanes.
4. And each lanes should be indivisually sizable.
 
FYI,
The behavior introduced since platinum.
X3 isn't perfect, however, at least it doesn't destroy workflow.
 
It's been few days that I contacted Cakewalk regarding the matter and I really hope to hear from them soon.
I'll update when I hear from them.

I much prefer the way the Track View handles MIDI controllers, especially when working with both audio and MIDI so I can stay in the same environment. 

Thank you for your suggestion Mr. Anderton.
I agree with that working with MIDI controllers in Track View is a nice way but it is still a workaround.
I actually use both PRV and Track View for editing but what I mentioned above is inefficiency of controller pane and want it to behave nicer at least as is in X3.
In the way as you suggested, you can't edit controllers very precisely in Event List. There are situations or users that need precise controller editing capability for controllers.
Cubase, Reaper and few others already offer the way I mentioned above for PRV controller pane.
I can't stress enough how basic and fundamental feature this is.
Hope Cakewalk fixes it very soon.

You might post this in the feature request forum if you haven't already.

There's one already regarding this matter by other forum member.
