## What it is
An Android library that simplifies creating system-level floating windows (overlays) over any app screen, with drag support, edge-snapping animations, and automatic permission handling. It offers a fluent chained API for positioning, per-activity visibility filtering, and multi-window management.

## Use cases
- show a floating widget over any screen in my android app
- create a draggable overlay button that snaps to the screen edge
- display a floating window without manually handling SYSTEM_ALERT_WINDOW permission
- show a floating view only on specific activities
- manage multiple floating windows in one app
- hide the floating window when the app goes to background

## When to choose
- you need an overlay/floating view across activities or the whole app on Android
- you want built-in drag, edge-snap animations, and permission request handling
- you need percentage-based sizing to adapt across screen resolutions

## When to avoid
- you only need an in-layout floating widget within a single screen (use regular views or CoordinatorLayout)
- you need a library actively updated for the latest Android versions (last release 2021)
- you target only Android 10+ where modern overlay APIs may be preferable
