Hi @Britney_Zpheres
You can slide all the shelves the same way that you can slide the left and right trays, except for the trays, you don’t have to hold Ctrl like you do for the shelves. Hold down Ctrl and move your cursor beside one of the icons or buttons on the right shelf, you will get an up/down arrow. When you get that, you can slide the shelf up or down. It’s kind of fiddly because the area to get the up/down arrow is small. If you “Enable Customize” and remove an icon from the right shelf, you can use that space to get the up/down arrow much easier. This works the same for all the shelves. Top, bottom left and right. Except, for the top and bottom shelves, it will be a left/right arrow
