ExtraDock is a macOS productivity app that lets you create unlimited custom floating docks and place them anywhere on your screen, transforming how you organize your workspace — especially on multi-monitor setups. ExtraDock was acquired by the developers of DockFlow. It was rebuilt from the ground up. ExtraDock 4.0 Launch marks a huge milestone for both ExtraDock and DockFlow as the apps are fully integrated with each other. Allowing even better workspace management and setup.
