Defraggler bar graph implementation

I really love the free space bars on Windows 7 that show a bar with percent free space on all the drives.

When you need to know at a glance, it just can't be beat.

A pie graph is simple, but you have to take a moment to decide which color is free space & which is used.

With a bar graph, the free space is immediately apparent!

Any chance of including a bar graph to show free space on drives? Having a choice of Bar or Pie would be great!

Defraggler shows numerical %used & % free space, but I was thinking it would be simpler instead of having 2 different sections, to just make Defraggler show 2 colors along a bar graph when it loads!

1 Color for Used, & 1 Color for empty! I think it would be so much simpler this way!

Users would not have to read the %, but can tell at a glance.

I hope this can be implemented, because I like how Windows 7 does the free space bar graphs in Windows Explorer!
