Is your feature request related to a problem? Please describe.

Imprecise scroll through artists to locate the one I'm looking for (without having to go through text search).
This is probably the only feature I miss from my previous music player (Rocket player): the ability to tap and hold to the right (where the scroll bar is) to scroll more quickly, and in particular to spot the first letter of the thing you are searching for (in my case, most of the time, artists, but that would apply to other views).

Describe the solution you'd like
I'd like to be able to tap and hold on the scroll bar to "jump" down the list of artists, instead of having to swipe many times (and inprecisely).
Ideally, when scrolling this way, I'd like the letters to appear as I scroll, to quickly and efficiently know I reached the place I was looking for.

A perfect example of the UI I have in mind is here: https://www.reddit.com/r/reactnative/comments/1iui9g2/implementing_an_alphabetical_scroller/

Thanks a lot for your great work!
