First of all it is a very nice program. I've used it since day 1.
One cool feature i find in other defragging tools is the screensaver mode. Take O&O or jkdefrag for instance.
I think that it would be relatively easy to transfer the code to run as a screensaver + it makes the tool even more useful for people who need an unnattended defrag when their computer is idle but do not want a permanently running process. ANyway the tool is great as it is.
uhm
