WINSUX  This application allows you to organize many types of media on the Web in a library. Like iTunes you can have (smart) folders and sort those by various criteria. Media types include images, portions of websites and flash games. The flash support makes this application extremely useful, if you like flash games. Not only that you can always access those games quickly, but you can also play in fullscreen and with various effects. Despite the low version number of 0.5 the application seem quite mature an ready for productive use. There are some minor bugs though. Unfortunately, it doesn't seem to support youtube videos, which would be a great enhancement. But all in all very promising, you will love it!
