I'm aware of bukkit plugins that allow you to "combine" items into new items, like the default settings in the linked plugin lets you combine a red flower and a white wool block into a red wool block.
I would like to integrate this into my server, but with increase scaling inefficiency. So you could change a stack of logs into a stack of signs with one click, but not the same number of signs that you would get making them individually. That is to balance the saved time.
However, I would like the option to allow people to use iConomy credits/cash/currency to offset that inefficiency if they choose. So then said stack of logs would turn into the exact amount of signs that it should make.
Does such a bukkit plugin exist?
