On my Roku2, the app displays folders and the files within them as lists; if the line item is longer than the provided on-screen length, the title automatically scrolls. Lovely. Perfect. Simple. Above all: Space efficient.
On my new Roku Ultra (2020 model, I think), the folders are displayed as large folder icons crammed together to permit four+ folders across and 1+ folders down. The titles of the folders, however, do not have enough space to permit them to be displayed in their entirety if they are longer than a few words. One must make a selection and then the selected folder's title will appear above the title icons so one knows what one has actually chosen. Then, when one goes into the chosen folder to view the enclosed file's titles, the same nonsense appears: Large icons with very little text and only when a title is selected does the full text of the title appear above the file icons.
I have a suggestion: Bring back the old user interface as an option. It's much more space efficient and is much quicker to navigate.
