Single post in Mass Item trading

Don't quote me on this, but I believe Niet has rejected this idea multiple times because he had offered something similar originally but there was a lot of pushback (i believe due to the fact that there would be conditions to it?), and now it's been so long that the whole trading system would now need to be reworked to allow this? However... I still personally think it's worth looking back into it, even if it requires either a rework of the trading system or a new solution entirely. Sending items can be a bit of a hassle. ;u; Even with gems, which have the small -> Medium -> large system for that reason, a lot of people still prefer to trade in mediums, so even those could benefit from being able to trade more at once, even though they have a workaround!
