@dominik we will look forward to get this merged.
@Eric_Delisle do suggest whether you wish to use this and initiate a merge or you can share your repo and we can initiate a merge.
@dominik, proposed contribution from your end Contribution Showcase: Delivery Service Tour - #2 by KanchanChauhan should consider options at delivery note level whether delivery is by Custom Mode, FedEx, UPS etc… and further it should capture relevant details as per respective service. Then we will plugin FedEx like your custom.
So, that will turn out to be a generic Logistic Manager. @rmehta has suggested similar updates in Pune Meetup as well.
