This plugin allows you to detect whether a user is idle on website or working. It will notify the user if he/she is idle for the time specified in the plugin's settings. The user will be given a choice whether he/she wants to continue working or not. If not than screen will be locked after the specified time. User will have to enter the password to continue working after that. Here, for the demo purpose, notifying time is set to 5s and timeout time is set to 30s. In real time application it should be much higher number.
