We use a domain policy that locks a computer when the screensaver kicks on at 5 minutes for security purposes. I sometimes use caffeine if I know that I'm going to be on a machine a while (but multi tasking so that I'm not using it sometimes for the 5 minutes). It would be an awesome feature to be able to activate per connection so that while I was on a computer it would keep the computer from locking.
Add my vote FOR this also. There are periods where I am not using the Host computer but I do not want the lock screen to activate with non use. I use other remote programs and no matter how long I have a Host computer minimized, when I focus back on it, the Host screen is right where I left it.
I am new to Remote Utilities and am currently evaluating it for further use. So far I am very impressed. It just needs some minor tweaks.
