Magic Screensaver Master is a program that can manage your screensaver behaviour. Just by positioning your mouse to a specific area on the screen (e.g. upper right corner) you can start your screensaver, disable screensaver, turn off monitor, log off, restart computer, or shut down the computer. User can customize the activation field (mouse sensitivity for actions) and the delay before each ection is launched.
Magic Screensaver Master is very lightweight and easy to set up and use. It doesn't come with bloatware and when installed, it takes less than 200 kB of space. That's why it's very fast and it doesn't take valuable resources.
