Roku can definitely be a challenge for older users. Short of using the newer Roku voice remotes that contain 2 programmable shortcut (Channel/app) buttons, kind of limited how to make it easier.
The voice remote will at least help with some of the navigation. Shortcut buttons beneficial to those that have a couple favorite channels they view regularly.
Only other method may be to create an illustrated guide/cheat sheet of what buttons to press to get to her programs.
