Jellyfin Android Client - Just show filenames

[TheDreadPirate]

The Music Videos library is pretty close.  Though I am not aware of a way to make Jellyfin show the actual file name.  You can change the video to a list by clicking on the "..." context menu at the top and change the "Image Type" to list.

I think that is as good as you're going to get for what you want.  You'd have to change the embedded title to match the file name to get exactly what you want.
