WindowLab

[2] In many aspects, WindowLab has looked to the Amiga's user interface for inspiration without cloning it completely.

This allows one, for example, to switch to a terminal to enter commands while keeping documentation visible in a web browser.

The developer states that many users find this faster than Mac OS X's Exposé feature.

This keeps the title bar widgets always accessible, and also mimics the Amiga's sliding "screens" functionality.

WindowLab has simplified task switching and app launching and no clock/calendar, status indicators or theming engine (although fonts and colors can be changed via command line options).
