Plex Media Player v2: Exclude Unused/Unwanted Navigation Categories

I don’t need to see dashboards for Music and Photos as I don’t have any libraries on my server or friends’ servers for those categories. Even if my friends did have libraries for these dashboards, I would want to exclude them from PMP. These should either only appear if there are libraries for those dashboards and we should be able to toggle them on or off in the settings menu.

I would also like this option. Seeing that we now have the option to reorder library categories it would seem logical to add the hide/show function to this area.

Early 2021 clean-up: implemented (unused categories no longer show on the home screen; libraries can be hidden from the main navigation)
