Windows Preview to OS X with HyperDock
One of the most useful improvements in the ‘user interface of Windows 7 is the bar of applications, in particular the thumbnails of windows applications open.
HyperDock Seven brings a feature in Mac OS X
This is a very convenient way of viewing and quick access to a specific window of an application, when you have several windows open.
Of course there is the function of Expose ‘on Mac OS X to manage thumbnails of windows applications, but many people find uncomfortable and jerky to use the preview feature as is the bar of Windows 7.
HyperDock, now in version beta, is free and allows Mac users to add the ‘style preview thumbnails for Mac OS X Dock, as shown above.
In addition to being able to view thumbnails, there are other useful features like the ability to control iTunes and display iCal events from within the thumbnails!
You can download the free beta of HyperDock now for Mac OS X 10.6 or higher.
