Sorry, quick p.s. after playing with it a little more. I found my new list under my user profile page. So, I need to create a new list with the link up top, then figure out that RePost at the bottom right really means Add To A List. Then, if I go to my own profile I can see my list, and can remove videos within it, but I haven't figured out how to remove the list itself yet. Now that I know all of this I can remember it, but I mostly figured it out by clicking random buttons. The user should be able to grok it from the labels and relative positions.
