example , remove channels that my wife does not watch on her E2 SE .

You can't remove channels from list

you can hide categories though

And you can create a "favorites" list, which can have ONLY the channels you want.  That's what I do.  I could not imagine for daily watching, to have to go through all the categories one by one each time.  By the time you go through them all, the programs are done and you have to start all over 🙂

I go through through the categories once, flag my favorites, and then always use my favorites for every day use after that.
