I don't use folders much... I don't find them helpful at the moment... Maybe if they displayed some kind of wave images in the folder's area instead of simple color bars I might use it... Probably too small to get an image with current resolution? ...
This is why I usually have (had) layers displayed within a track of equal height as my others ((F)...
Now if the track displayed only the selected clips (as it appeared it did in the video), I could probably enjoy the lanes more... right now when I collapse the lanes I typically have muted clips on top of the active clip as I did in X1. Maybe this is a bug? I will write it up as a bug unless I hear (quickly) that it is operating as expected in this manner... Then I will put in a feature request! ;-)

You're in for some treats, some improvements, and some frustration... Hopefully mostly the first two. Getting used to the new paradigm and finding what works for you and what doesn't...
In the end I think you'll find it a worthwhile experience... I have my joys, as well as my complaints with the X series, but it works well and has some fabulous abilities!
