Disk Usage Statistics

The file system view gives a good overview of disk space, but there isn't any way to drill down and view the disk usage at a more detailed level.

A simple implementation would let the user drill down each folder and view the size of the sub-folders and files within, e.g. du -ch --max-depth=1.

Taking this idea even further;

• Percentages of overall space (in a tree view)
• Summary by File Extension
• Graph/Block visualization
