Add timeout function to snippets
Like MTPutty, add functionality for a timeout to be specified when a snippet is running. A simple sleep would not be sufficient in this case because the terminal would be busy and could not run a sleep command.
In my case, I have a java applet that is used by others. I like to broadcast that the applet will reboot, followed by 5 minutes of warnings sent every 60 seconds. Since the applet does not support sleeping between commands, and I do not have the time to manually do it, I feel that this functionality would be very useful.
