You can use the plugin by doing /wb, /craft, and /open.
Open Workbench- craft.open
PortableCrafting allows you to use the command /wb to open a workbench! You can be anywhere anytime and just use the command /wb. The plugin will have a lot more features to come such as /furnace to open a furnace, /enchant to open an enchantment table, and /chest to open a chest! I will also try to code for admins to open workbenches, furnaces and enchanters for other players!
