I thought this answer was a bit unGoogleable. After upgrading StackExchange’s Mini Profiler I noticed an ‘m’ and ‘c’ at the button. But their use isn’t incredible clear. It turns out, the ‘m’ is minimize/maximize, which is great for those pesky situations where it’s covering a piece of the page you need to see. The ‘c’ button is “clear”: it clears the results. It would have been helpful if there was a tooltip for these, because just randomly clicking both to see what they do is pretty confusing.
