How do I turn off the popup notification about reformating code?

When I started using Phpstorm EAP 9; I noticed that every time I reformat code there appears a little popup telling me that I reformated the code. Thank you very much for distracting me by telling me that you did what I told you to do Phpstorm.

Is there any way to turn it off?
I can't fathom why anyone ever thought this was a good idea; but I hate notifications more than most. Unless something is on fire; just log it and I'll look when I have the time.
