Flatsonar is just the shop window. The people below made Region to Share.
About
Region-to-Share lets you select a specific area of your screen and display it in a dedicated window that you can share directly in video conferencing applications such as Google Meet, Teams, Discord, or Zoom. This is especially useful for ultra-wide (21:9, 32:9) or multi-monitor setups where sharing the full screen would expose too much, or where you only want to share one application region without switching windows. Features: - Interactive region selection with real-time preview - High-performance real-time display (native Rust, low CPU usage) - Native Wayland support via XDG Desktop Portal / PipeWire - Native X11 support - Modern egui interface - Adjustable window opacity - Performance monitoring overlay - Remembers last selected region
