I Use the filters (processing ,completed etc) to filter out my views. There is quite a convoluted way to invoice, ship order resulting in 3 separate ref numbers. Really over complicated but works ok. The problem is incomplete orders are getting mixed into the mess and still for some reason Magento dosent want to allow DELETE ORDER facility.
Got through Christmas with 170 orders. Been using Credit memos too.
Happy Christmas and cant wait for digital goods update!!!!!
