Works well as a monitor...one suggestion...when you click it, it should open the associated drive. The way it is now, I need to have a shortcut icon to my drive on the dock along with your monitor icon...if your monitor docklet could open the drive when clicked, I could eliminate one icon per drive. Also, maybe a "nice to have" feature, but not necessary. I like to show total space and free space available only (no used space). When a person only checks one or the other of "free space" or "used space", but not both, you should center the text on the icon instead of leaving it left or right justified...it looks unbalanced when only one value is displayed...hope you understood that.
