Coloring of file/folder size units

[ThiefMaster]

It would be great if there was an option to color the size units in the file list - especially when viewing the size of all folders (shift+alt+enter).
For example, I'd like to display G in a different color so I can easily see which folders are very big when cleaning up drives.

In principle it would be possible, but currently the entire line is drawn with the same (default or custom) color.
