Give some sort of gui representation of defrag
With the other defrag programs there is a gui to give you an idea of how much defragging was remaining and how much progress is made. It would help you to know if defrag is stuck.

Probably referring to the old '98 defrag tool that visualized blocks on disk to let you "see" how fragmented the disk was. Admittedly there was something satisfying about watching those little red squares turn into green ones as the disk was defragmented.
Please explain more. The defrag in Windows 10 does give progress, for instance, so I don't know what you're asking for.
