Allow custom ordering of package/box sizes list. This would make it much easier if you can set it up in the order that works best for your shipments. Currently, I have boxes that are broken down into multiple sizes, but SE moves them out of order which is very annoying and inconvenient. It also makes for potential errors by selecting the wrong box as it's not in the correct flow order. Moving the most used boxes to the top of the list would be great.
