Separating it from the main window makes it easier to place on the desktop.

The Log window is designed to stay open all the time when the program is working, and it displays important information about your tasks. ImgBurn's two-part interface displays controls and the program's log file in separate windows. What ImgBurn does is simplify what can be a complicated, error-prone process. This lightweight freeware burns CDs, DVDs, HD-DVDs, and Blu-Ray discs, depending of course on your system's capabilities: You'll need a Blu-Ray burner to burn Blu-Ray discs with ImgBurn, for example, just like with every other disc-burning tool. However, to make all that easy, you need help in the form of a good disc-burning utility. If your PC has an optical disc burner like a DVD or Blu-Ray burner, you can create DVDs that you can play in your home entertainment system, boot discs that can help you start your PC when something goes wrong, and data discs that can safely store backups, archives, disk images and copies, and other data.
