This add-on synchronizes the camera angle and perspective of multiple 3D viewports in real time. Users can selectively link viewports together while maintaining independent display settings, allowing for side-by-side comparisons like viewing a wireframe mesh next to a material preview. It provides three synchronization scopes: linking viewports within a single window, across an entire workspace including multiple windows, or globally throughout the entire blend file. It also includes performance toggles to pause synchronization globally, pause it automatically during animation playback, or disable it for viewports currently in camera view.
