I know there are people who have problems with indenting and outdenting the elements in that tree, not with just moving them up or down. I had some problems to begin with, but not so any more. It wouldn't harm though, if CC made it easier for newbies, so I'm all for putting that on the list.

Inger highlights the indent and outdenting issue that is difficult. For me there seems to be some sort of trip to indent and outdent that I can't seem to master
Lots of dragging above and then brining up the lower item above that item... a bit confusing for this old guy.
