I am pretty sure that it didn't warn me that a restart will be required when I run the "Clean" Feature. I am not an uptime freak, but it would be nice to be informed ahead of time that I am going to have to restart everything else going on on my computer. I log into a number of different applications and servers to start my day.
I am also not excited about having to pay $10 for a feature. That is "Demoware" in my book. Other than that, I think the application is pretty straightforward.
