In a recent version of the cart (I'd say about 10 versions ago, so maybe 4.40 or something) there were security roles that could be set so that when particular users logged into the store, they could manage only certain modules. For me, these were 'Manage Orders', and 'Manage Shipments', with the corresponding security roles; SCManageOrders, SCShipOrders.
Since upgrading the cart, when logging in to the store to administer orders, the red toolbox that is used to access the store admin menu is gone when I login with a user that is a part of the said security roles.
Cart version 4.52, dnn 5.5.1, sql 2008
