Meblin made a great insert, but storing vertically was an issue. I made a tray to hold the player boards, play aids and score pad. The new tray completely covers the bottom trays and allows vertical storage without the money and other bits going all over the place.
CAUTION: It appears there are different versions of the player boards. The player boards in my edition (purchased in February 2019 from Amazon US) have the wheat icons aligned horizontally. Other editions have the wheat icons aligned vertically. This tray will only work with the smaller player boards with the horizontally aligned wheat icons. See the comments of an picture of the larger player boards that don't fit.
