What is this icon? There’s no tool-tip if you hover over it and if I click on it, nothing happens.

It will return the Dashboard panels to the default arrangement. Useful, if you have resized them or shuffled them around and one has disappeared. It likely has gone offscreen. Clicking the button brings back all of the panels to default layout and visible.
