Is there any way to change the showcase mode (f5)?

I love the app, but I would like there to be a way to change the way the showcase mode is displayed. 

I don't know if it can be customized right now, but if so, I would love to know how.

Also, it would be great if there were a way to enter an album mode where there is only one album and it doesn't belong to the entire playlist of Jellyfin media.

Thank you!
