How does this function work

[gaojunyang666]

Dear developer hello, this is a very practical and excellent plug-in, but I encountered the following confusion in the process of using:
How does this function work :"Automatically hide ribbon and status bar items once your mouse leaves the icon container"
I do not know how to use the function, what is the difference between turning on or off, I hope you can share the operation manual to introduce this function of the plug-in
