A pointer-following GNOME magnifier (Bildschirmlupe, Bildschirmvergrößerung) for large and multi-monitor desktops. Customize the lens shape, size, frame color and thickness. Includes keyboard shortcuts and adjustable zoom steps. Use Ctrl+Super+scroll wheel to zoom, or Shift+Ctrl+Super+scroll wheel to resize the lens. Rectangles scale proportionally; round shapes change their radius, with size limits suited to the current monitor. Both modifier combinations are configurable, with separate on/off switches in preferences.
