as it is right now you can max trade 400/400 and i have been thinking about how about making it so you can trade more, so us who want to trade like 4k+ are able to send it like 1000/1000 or more, and make some sort of cost to be able to do so.
Or make a building that lets you trade bigger amounts, since having to keep track of how much you have sent and keep sending the same over and over again, it gets quite annoying in the end, hope its something that can be considered
