Plex is working on adding something of a more traditional Grid View. This of course would make channel changing much easier when you know what channel you wish to watch.
I’m the same way, in that I watch a lot of CNN and Fox News with some MSNBC mixed in here and there. I always know the exact channel I wan to watch and they are all right next to each other. Would make for simple “up/down” commands on the remote (like normal TV) or hit the grid view for channel change.
I have no idea of the timeline but do know it’s been announced here in the forums so the end is in sight.
