I have the modern interface and have added three titles to it. The I laid them out in order of importance to me from left to right. The order is Connections, Activities, Devices. If I resize the browser window to make it narrower, the first row contains Devices followed by Connections, then the second row has Activities.
This is unexpected. I expected Devices to be wrapped around to the second line. I positioning Devices on the second row (strangely I couldn't put it under Connections, but only under Activities), but that didn't help when I resized the window. Devices ended up at the top left again.
In fact the layout of the tiles seems completely random as you resize the window.
