Hey Guys,
i actually started this topic today : Is there a need for a kirby-based Shop System? now i was pointed to your project. Seems like you folks did a great job. Is https://github.com/getkart/kart/ the most recent status of the project? @plaidpowered are you the owner of the repository?
edit: Just read that the development has been stopped. I will most likely set up an own solution and see this as an inspiration. Anyone that is willing to contribute is very welcome to join.
