One of my other primary tools incorporated a docking system in the early 00s. Hate, hate, hated it...until one day the proverbial light bulb went off and I seemed to understand what the developers were trying to provide. After that it became a serious infatuation and is now so incorporated into my thinking that I don't think I could live with out it...or I could but why would I?
When Cakewalk was demoing the upcoming features in X1 and I saw the multi-dock I was thinking tres magnifique amigos! Personally I love the multi-dock, it's there if I need it and I can bypass it if I want to. I can float windows if need be or I can dock them.
What I really disliked was the inability to manage all the window in 8.5. It used to drive me bonkers. If Sonar was still set up solely like that I would have moved on to a different DAW.
Just saying...
Regards,
