The dots are also drag handles. Originally I made them disclosure rects, I just think the dots look a little cleaner and since they can be used for both collapsing and dragging I think generic was a little more appropriate too. Can you explain more on "can't drag an outline to the bottom of the file?". I think that should be possible.
