I tried this last night .. as we run 3 different Stores - the idea behind this is great .. and it does indeed pull all my orders into one place - however we cannot use it.
It has a couple of crucial parts missing for our work flow, the ability to print multiple orders at one time .. and also to use order printer and its Invoice templates for that printing .. if these options could be added .. we would definitely use this, so sadly its not for us .. we take our order list tick them all then print them all at once with Order Printer and a template that puts the label on an integrated sticky label we use.
If this is not your workflow .. and you are happy to deal with each order individually .. this would probably be excellent.
any chance of those features being added? you would have a customer for sure!
