Please consider adding the option of printing most of the pick list on the USPS shipping label.
It currently prints the order ID which is rather useless since you still have to refer to the order on the computer.
This would save paper/ink since we won't have to print a separate pick list.
It can print the order options or SKU depending on the store it is pulling the order from.
This is so simple, I'll help you code it if necessary

Please Please Please

Great news! We have a new feature that I think this may meet your needs! You can now customize your labels a bit more. Our new templates allow for more information as seen here: How to: Customize USPS domestic shipping labels
It is not quite a "Pick List" replacement, but may help your process.
