watch lists - XFinity

For watch lists, XFinity-Comcast Television Apps which include TV Go. OK. I try to find out about watch lists, and I am directed to the new Xfinity TV app with a description of how wonderful it is. Well as far as I'm concerned, it is not wonderful without a usable watchlist that can handle a sizable list of programs that I can arrange as I need. Please - can I keep the old app going until you add this to you new, wonderful app.
