Hey, i am running a small server for me and my class mates. Are there any suggestions for a basic lightweight shop (gui) plugin that allows you to buy or trade certain vanilla items for others. eg. 128 mutton and 128 wool for a sheep spawn egg and a few similiar trades but for other spawn eggs and maybe elytra. Am running a paper spigot server on minecraft 1.17. Thanks in advance! have a good day.
