Drag the left menu into your own order. Hold a row and drag it up or down. On a computer, pointing at a row shows six faint dots at its right edge: that's the sign it can be dragged. Each section keeps its own order (your Tour menu and your Money menu are different). Once you've moved something, a small circular-arrow button next to the section name puts that section back in its normal order.
IT FOLLOWS YOUR LOGIN: the order is saved to your account, so the website, the iPhone app and the Mac app all show it. A device that's already open picks it up when you come back to its window.
NEW FEATURES: a menu item ATOM adds later shows up at the bottom of your custom order, so you never miss it. Drag it where you want it.
