Warning befoor shutting down a LS computer


On the mac version it seems there is an issue with the host thinking that there is no activity, even if there is (i was trying out Avorion). After 30 minutes i get booted and the host shuts down. If there would be a modal popup warning that says "there is no input detected for 29 minutes, click here if you want to extend your session, or do nothing and your LS computer will shut down in 60 seconds" then this would not be a big problem as it is now.
Even better if it would be properly detected that there is input ofcourse...
