Ability to sort, filter and other improvements to library

[maxsubs]

I have a very large library, mostly albums, so scrolling through the artists, albums and songs is a pain. I'd like to suggest some things to make the experience even better:

• Add sorting options to Artists, Albums, Songs and Playlists such as, by added date, release date (Albums), number of songs (Albums/Artists), name. All of them with the options of reverse sorting.

• ✔ Add filters: So if you have many albums, chances are, some of them may have featuring artists/collaborations and that will add up the amount of artists to your library with many artists with only one or very few songs, cause they only feature in a song of an album, which would make your Artists section huge, it'd be nice to be able to filter artists by number of songs, so you can hide, say, artists with less than 5 songs. Some other filtering idea could be by genre (Artists/Albums).

• Add fast scrolling on the right edge of the screen with an indicating letter popping out as you scroll.

• ✔ Don't go back to the top whenever you open an artist/album/playlist and go back to the main section, i.e. if you go down on your artists library an open Elvis Presley and then go back, it will go to the top of your artists section.

• ❌ Make the Sinchronize button consistent on landscape and vertical view. On landscape view, you get to see the icon, whether on vertical view you have to click on the 3 dots tor an option on the menu.

These are only ideas, I don't know to what extent they can be implemented or not, I'd write more ideas and hopefully I could contribute to something, like the Spanish translation, let me know if needed. I'm enjoying a lot this software :)

This should already be the case ; if you see the 3 dots in vertical mode on your device, it means that your device has a resolution horizontally too low to display all buttons and the system chose to collapse them...

Fast scroll is actually already enabled ; the only thing missing is the letters popping during scroll. I'm not sure how to implement that.

As for why the experience can be unpleasant using fast scroll, it is related to an Android issue with the RecyclerView component : https://issuetracker.google.com/issues/64729576

This makes fastscroll unusable when used in a RecyclerView with many elements.

There are multiple techniques and external libraries out there that can be implemented to keep the 'thumb' at a nice size, but i'm not sure how to implement them.
I'll try to look into it :)
