Since you can download a list of APPS and Antenna / Cable Channels, the live streaming channels are the only ones that we do not have access to and from what I've seen these change on a monthly basis.
I built my own desktop app and having the ability to download all the apps/channels let's me create shortcuts to content and deep linking has made that even better. It's easy to have over 1000 channels available if you count the live channels in apps like Pluto, Tubi, Peacock and others along with cable. It's hard to even know what all is available and manage it within the individual apps. Since I built my app I'm watching content that I never watched before simply because I didn't know what was there.
