The program lets you establish download queues by order of priority, for any series of files that you import. You can also resume downloads in case you had to interrupt them halfway because you had to disconnect from the Internet or because the connection was cut off.
You just have to copy and paste the files that you want to download into the program's main window, and it will do the rest by itself. That said, it can't take download from services like Megaupload and Rapidshare.
uGet helps you control your downloads better, making it easier in general.
Requires having GTK2 installed
