Features: - Right-click the menu bar icon to quickly activate. - Choose to activate with left-click instead in the Preferences. - Choose to activate at launch in the Preferences. - Allow the display to sleep in the Preferences. - Set the default duration in the Preferences, which is used when Lungo is activated by clicking the menu bar icon. - Control Lungo from scripts or the terminal. (See the website for more info) Important: Lungo will not prevent your Mac from sleeping if you close the lid. This is a Mac App Store limitation.
