Kinsman Screen Clip Viewer

Features

Ever wish you could zoom into a part of your screen and keep it visible while you work? Kinsman Screen Clip Viewer captures any region of your display and shows it in a resizable, always-on-top floating window.

Built for a real use case: monitoring a game (MTGA) in Stage Manager thumbnails to see when it's your turn, while working in other apps.

Four Zoom Modes

• Stage Manager — Zoom the left or right sidebar strip. Use Focus to crop to a single thumbnail, then lock it in place.
• Follow Mouse — The zoom follows your cursor in real-time. Press Cmd+Shift+L to lock the position.
• Track App — Automatically follows a specific app's window as it moves.
• Fixed Region — Manually select any rectangular area of your screen to zoom.

Floating PiP Window

• Pop out the zoomed view to a floating always-on-top panel
• Independent zoom control (1x–6x) with scroll/pan when zoomed in
• Built-in controls: start/stop, zoom, lock, focus, and mode picker
• Stays visible across all Spaces and fullscreen apps

More Features

• Universal Lock — Lock the zoom position in any mode (Cmd+Shift+L global hotkey)

• Adjustable Zoom — 1x to 8x in the main window
• Region Picker — Click and drag overlay to select screen areas
• App Sandbox — Runs in macOS App Sandbox for security
