Zoom and pan the current darkroom image.
At the top of the darkroom left panel, the navigation module shows a full preview of the current image with a rectangle marking the area currently visible in the center view. Drag the rectangle to pan the zoomed-in view.
The current zoom level is displayed to the right of the preview. Click it for quick access to common zoom levels.
The module can be expanded/collapsed like any toolbox — from its header, through the global action search, or via a shortcut you assign to its focusing action. Center-view zoom is also controlled directly: see zoom and pan.
