This is a slightly different channel surfing question than I have seen before. since the Search option appears to search all of the installed channels for the show you're looking for, it seems there's some way for a Roku device or some part of the Roku "back end" to be informed of everything on those channels. SO - can there be a similar "Live TV" option that is aware of all of the Live TV 'subchannels' (for lack of a better word) offered by the various installed channels, organizes them into a list, and that can be scrolled through similar to channel surfing with a cable remote?
