Single post in Trades need more item slots

Suggestion Title: Trades Need More Item Slots Suggestion Summary: As of the moment, trades only have a maximum of 5 slots, I believe bumping it up to at least 10, or removing the maximum altogether would be a good idea Positive points: 1. Lots of people trade more than 5 items at a time, so much so that it becomes a habit to trade the rest as gifts 2. Running a trade shop, would be infinite times easier Negative points: 1. Although there are things such as boxboxes and medium/large gems for compact storage, there are other items like summons and almost every other item doesn't have any way to compact them. Reason For Consideration: I think every trade shop owner would enjoy this one, and trades haven't been changed in years from what I have heard
