Enabling autosave on Sublime Text Editor

I am using the Sublime editor on Mac. But I have to manually save the file. And when the editor is closed it asks whether to save the file or not. Is there a way to make it behave like Notepad++? **Desired Behavior:** Sublime Text should close without asking anything and when reopened it should preserve the open texts files **Things I tried:** Opened Settings and added hot_exit: true but this didn't have any effect. The following pic shows the settings:
