option to limit side menu tags (artists and lists of tags) to the library you are in.

[CuddleBear92]

like the title says, enable the side menu with the tag list and artist list to only display things from the library you are in.... favorites and the library (could get more later ofc).
makes it easier to find the tags and artists and so on that you want as you are narrowing things down by aton.

there should be a button either on top with the tabs inside the side menu or in the settings to set a default.

Sounds really useful actually.
