I would like a Favorite channel folder option and/or folder category option that allows me to sort different channels into folders so I don't have to scroll through hundreds to get to what I want. Ie Pluto, Roku, Peacock, Netflix might be in a Favorite folder, all horror in another and all comedy in another and children etc. as well as all channels available.
I don't know if it still works, but you can try "My Channels": https://my.roku.com/add/MyChannels
Also, you know that you can rearrange channels on the Home Screen, right?
