you can't sort out your HD channels with Hooper 3 so far. You can make a favorites list pretty easily. I did it and I like it more than I thought I would. You can't save locals in this list. Yet.
I noticed that. My OTA channels would not save in my favs.
This thing was not ready for primetime, sorry. Too many features missing the early upgraders were used to. It has a lot of pros, and a lot of cons.
