## What it is
An Android UI widget library that adds a fast-scrolling scrollbar to RecyclerViews, with an optional section indicator like the Lollipop Contacts app. It is distributed via Maven Central and written in Java.

## Use cases
- add a fast scroller to a long RecyclerView list
- show a section indicator bubble while scrolling contacts alphabetically
- let users drag a scrollbar handle to jump through large lists
- sync scrollbar position with RecyclerView scroll events

## When to choose
- you have a long Android RecyclerView list that needs quick navigation
- you want a Lollipop Contacts-style section indicator
- you need a simple drop-in XML widget for RecyclerView scrolling

## When to avoid
- your project uses Jetpack Compose instead of View-based RecyclerView
- you need horizontal fast scrolling (only vertical is implemented)
- you need an actively maintained library with recent updates
