There are not enough plugin settings

Hi!

I accidentally found your plugin and its idea is very good, but there is a lack of a chain of movement between order statuses. We have the statuses of packaging, delivery to the courier and so on… It would be nice to add the possibility of settings in the plugin to move orders between statuses. Now it is more suitable for restaurants, but there is also no way to print a delivery receipt or document. The order immediately goes to completed, it turns out there is no delivery process.. But the idea is very good.
