## What it is
A Windows desktop utility that shows a real-time, always-on-top replica of any window you choose, built on native DWM thumbnails. It supports subregion selection, click forwarding, click-through overlays, opacity, and auto-resizing.

## Use cases
- keep a window always on top while working in other apps
- watch a video in a small overlay while working
- monitor a background process window in real time
- clone a region of a game window as an overlay
- interact with a cloned window via click forwarding
- create a click-through semi-transparent overlay of an app

## When to choose
- you need a picture-in-picture clone of any Windows application window
- you want to monitor a background tool without switching windows
- you need a lightweight, native DWM-based window thumbnail tool

## When to avoid
- you are not on Windows or lack Desktop Composition (Aero)
- you need to clone full applications rather than window thumbnails
- you need High DPI support, which is still incomplete
