I still can't deal with the left-hand column layout of how Take Lanes are implemented, because I still get lost in the layout easily, but I do like the new comping abilities, and like the
Flatten Comp feature. Pretty cool stuff.
Personally, I don't understand why a single Take Lane will leave the Track picture blank if you expand it vs. if you have two Take Lanes (one blank and the other with music). In other words, for a Track that has a single Take Lane, expand it to show the Lane. The track is blank. Now, click the "+" button on the Take Lane to add a new one. Now the Track picture is drawn. I don't see this as a problem, but something that could have been done with a little more attention.
I also don't understand why the Take Lane default color couldn't have been lighter or darker by default than the color of the Track. Just doesn't make sense to me.
How to insert split lines to begin comping isn't intuitive, so I had to go back and review the video to learn how to add them, but it's probably much better (after I get used to it) to comp with than X2's abilities.
