Add more space when trading

[Beanmachine]

When we have to sell more than 4 things at once, we cant. Plz make it like before and also people can show their items quicker and easier.

That what happens when people do this word which I like to call... "complain", look it up, it's quite fascinating.. I rest my case.

I dont gwt the idea

It used to have way more than 4 item slots, but they limited it to 4 because some noobs wouldn't see they had a second page of items, and they wanted to trade 4 or so items to someone, but forgot about the second page and didn't notice it so they traded more than intended. They should've just added a warning IMO, but it doesn't matter to me at all anymore since CS is out.
