Original defrag tended to chain clusters from big files, it would be nice to add a color code like Norton Disk Doctor's to locate big file chunks to be able to arrange them and get some "points" maybe?  and have some sort of Final score and a Leaderboard?

Original program cannot handle unmovable system/hidden files. Along with the total files occupation it would be nice to have them selectable in the options just like the bad sectors are.

A time attack mode? Keep up the good work! I Love the case chime!

Thank you for your feedback!

I refrained from adding leaderboards and the concept of scores because it didn't feel really "zen" to me, but one can indeed make use of the "elapsed time" in the bottom left of the screen for personal challenge purposes, if they so wish!

I was thinking about including unmovable files too, so thanks for reminding me about it. I will eventually need to rework the UI a bit, so to fit all the features as they come up!
