G.E.L. -
You are not alone. Many folks, long-time SONAR users, do not "get" the multidock, and do not see it as an improvement.
This doesn't make them stupid. About the worst you could say is that they are unwilling to change or compromise.
In my case, I do not appreciate that the multidock is better than the window management in SONAR 8.x, and there is nothing else in the X1 release that compensates for the negative aspects of multidock, in my opinion.
The SonarPlus utility mentioned above goes quite a long way to reducing the negative aspects of the multidock. I'd say "check it out" but with X1D on the horizon, we have no guarantee that SonarPlus will be updated (it is version-specific).
