Very good idea to have a wish list for this excellent software.
Here is my suggestion:
1- It would be nice to show in different colors the folders, in order to differenciate them from the files.
2- It would be great to have the option "arrange the folders together in the fastest part of the disk" or something similar.
3- Missing colors in the color map.
There are some colors like light blue and light red (or orange colors), that are not explained in the color map.
4- It would be good to estimate how much time the defragmentation process will take.
5- It would be nice to have a time counter, in order to check how much time the defragmentation process is taking or took if already finished.
Sorry if I'm asking too much.
Thank's,
