Easier Order Tracking Number
Your Canada Post plug-in does not offer a good tracking number integration. I currently use a Canada Post plug-in from CodeCanyon which has a simple box on the back-end order page that the tracking number(s) can be pasted into. It immediately looks up the tracking information and pulls the data from Canada Post and will refresh as needed. This is so simple and should be implemented in all shipping plugins. This is the only thing stopping me from switching to your plug-in.
