Raskin is an alternative desktop interface for Mac that allows you to display all your documents and open apps in one zoomable surface. This unique interface reduces window clutter and makes finding, organizing, previewing, and opening documents much quicker. With Raskin, there's no need to navigate through deep folder structures or remember file names - all your files and folders are displayed openly with full previews. You can easily zoom in for a closer look using trackpad gestures.
While Raskin can be seen as a complement to Finder and Exposé, it offers some additional features such as organizing photos on memory cards. However, if you already use Exposé, Raskin may not be essential. Overall, Raskin is an interesting addition to your desktop browsing experience, providing a plain overview of your desktop and open apps.
