OnTopReplica

A real-time always-on-top “replica” of a window of your choice, for Windows Vista, 7, 8, or 10.

This simple utility application shows a blank always-on-top window by default. Users can pick any other window of the system to have an always up-to-date clone of the target window shown always-on-top. Very useful for monitoring background processes, wrangling with complex multi-window games or tools, watching Youtube videos while working, and so on.

📢 Features:

• Clone any of your windows and keep it always-on-top while working with other windows,
• Select a subregion of the cloned window, which:
  • Can be stored for future use,
  • Can use relative coordinates from the target window’s borders.
• Auto-resizing (fit the original window, half, quarter and fullscreen mode),
• Position lock on any corner of your screen,
• Adjustable opacity,
• “Click forwarding”: allows to interact with the cloned window,
• “Click-through”: makes the replica ignore any mouse interaction (turns OnTopReplica into an overlay if set together with partial opacity),
• “Group switch”-mode automatically switches through a group of windows while you use them.

Requirements

• Microsoft Windows Vista or greater (the application makes use of native DWM Thumbnails to create replicas),
• Microsoft .NET Framework 4.7.
• Desktop Composition (a.k.a. Windows Aero) enabled.

Installation

Get the latest version from the releases section as an MSI installer.

Roadmap

1. ✅ Update to the newest WindowsFormsAero version.
2. ✅ Migrate to .NET 4.7.
3. Improve/add High DPI support!
4. “Stored scenarios” that, just like stored regions, automatically clone a window (based on title or window class criteria), select a region, and set other options. Ideally to be used as Taskbar shortlinks.
5. Move to the Windows Store, via Centennial. 🤞
