Funny, I tried to post a comment here last week, but I see it's gone now. It wasn't offensive or anything, so I can't see any reason that it would have been deleted. Whatever the case, I suggested in that comment that the dev change the demo mode so the 100 minutes don't keep counting down if the computer is idle. I started demoing this app, went to have dinner, then when I came back, the demo was expired and I had no chance to really evaluate the app. I should have quit the app before I left the computer, but, frankly, I don't think this is a very user-friendly model. After all, quitting a background utility every time I walk away from my machine is hardly habitual behaviour. I think that having the demo timer pause after, say, five minutes of idle time would be very helpful.
