Currently at version 0.7.1, Brasero impresses with a simple layout and an intuitive interface. The left panel contains a file browser from which you can select the files/folders which you want on your CD, and in the right panel you can visualize what files are to be written. Of course, for ease of use, you can drag and drop files from the file browser to the right panel. You can toggle the side panel using F7, and hide it if it stays in your way.
