Nulana has launched Flexiglass (http://nulana.com/flexiglass), an application for management of Mac OS X windows. It requires an Intel-based Mac running Mac OS X 10.5 or higher and costs US$7.99.
With Flexiglass, windows can be moved, resized, maximized and closed with a mouse, trackpad multi-touch gestures, and keyboard shortcuts. Application settings can be modified to move and resize, real zoom and quick layouts to suit user needs and preferences.
Flexiglass supports English, French, German, Japanese, Russian, and Spanish. A demo is available for download.
