When selecting a channel from the "All channels" list, it's very cumbersome to scroll through the nearly 150 channels that I receive via DirectTV. I know, I know - I could navigate using the shorting listing of favorite channels, but I would still end up with a rather large number of channels in that category.

Why not allow the user the option to categorize the channels by genre, i.e. sports, news, music, local, movies, etc. ?
