Mosaic is a powerful window manager that allows easy repositioning and resizing of macOS apps, transforming multi-window chaos into a productive suite of tools. Mosaic has been meticulously designed to feel like an integrated component of macOS -- and not like a standalone app. The result is a seamless and intuitive experience that feels as good to use as it looks. Rather than limit you to a list of simple preset layouts, Mosaic lets you create any layout you like with a powerful suite of layout creation tools. You can simply paint a layout on a grid or achieve absolute control with numerical constraints.
