Another little something I have been working on..

[Jafula]

I've added two new slash commands based on your requests. Both these commands require the trade window to be open.

/jamba-trade loadname <item-name>,<amount>

This will split the item into a stack of the required amount and then load that stack into the trade window.

Edit2: Don't forget you can shift click an item to put it into the chat edit box. So typing "/jamba trade loadname " <shift click an item in your bags> ", 5" works.

/jamba-trade loadname Raw Rainbow Fin Albacore, 5

/jamba-trade loadtype <class>,<subclass>

This will load as many items of the request type that can be found into the trade window.

/jamba-trade loadtype Trade Goods, Meat

Example that works (but badly as the key needs to be spammed a few times because we have to wait for the trade window to load).

/run InitiateTrade("Jaaria")
/jamba-trade loadtype Trade Goods, Meat
/run AcceptTrade()

Edit: You'll need to action these on the actual toon, the commands don't have tag parameters, so they won't work across the addon channel.
