Channels Seach in the Guide / On Now

Now that we have so many various source input options it would be nice if we could search (and then save the search filter) for a channel either by channel number or by name similar to what we have when using the web based GUI when searching for content. The would help with the display of the guide if we could basically filter the guide by either a channel number range or by name/call letters.

It would be great if this would also be available on the apps in addition to the Web UI.
