100% on board with that, I use the server side settings to make all clients (only 2) look and act the same, and be as simple and non-redundant as possible. only have the guide, recordings, tv shows, and movies showing on the left side. I prefer the guide drop-down box hidden but lately I've been playing with the channel collections, using the dropdown to choose from them. I have Antenna, Xfinity, PBS, Stirr, Pluto, and Samsung+ but for some reason channels from one collection will show in another one. The stirr channels don't show at all to be added to a collection. Having several large collections doesn't seem to work as planned. Swear I thought there was a way to have the sources in that dropdown, and not need the collections. Anyways, that's a different issue I need to look into.
I envision that if you have someone install channels, and the dropdown is hidden by default it's going to show all channels, and you'll have to do this again on that client to show only the favorites.
