Feel free to move this request to wherever it belongs. Your system for submitting requests is convoluted at best, and sucks at worst :)
Please implement a checkbox next to all orders, and a "unarchive/archive all checked" button. Archiving them one at a time is tedious, to say the least.
Also, the total number of archived orders should not be limited to 100 as it is currently - after all, the number of orders in the whole history is not. I would like to clean up my order list to only things that have not been delivered or other relevant criteria. Because I can only archive 100 orders, even when I archive an order, the list gets refilled from all other orders in the history, so the main order page is always full, even when some orders have been delivered and there are orders on page 2 (3..4...) that are still pending delivery.
Actually deleting from the visible list would also be nice, using the same checkbox and adding a "Delete Permanently" option.
