This is a to-do that’s been on the books since I introduced congos on HC. Now the congo admin can easily reorder the congo stores from the “Edit vendor” page. The stores are now ordered by category order, rather than the category number. So to re-order the stores, just enter numbers into the “Category Order” field in the numerical order you like. This will change the order of the stores on your main congo page. The same holds true for regular store categories as well. The numbers don’t have to be sequential (in other words, you can skip numbers and enter 10, 20, 30, etc.). Do be careful not to repeat a number though.
Now you can easily put guest vendors at the top of your store, circulate store order week-to-week, feature a particular store at the top, etc. etc.
