I agree that the two items mentioned above are needed and I would also add:
3. Defrag the files/folder and Freespace with one button click.
4. Include a legend to the colored squares.
5. Auto expand the width/height of the available drives.
6. I presume that if Defraggler was run in Safe mode or when first booting up, it would be able to access all system files, the registry, the PageFile, etc so I'd like to have a couple of options for defraggmenting such as Simple (what it does now plus defragging Freespace) and Advanced (where if restarts the PC automatically).
