This event has made it clearer than ever that we need some kind of stacking / grouping option when creating or offering on trades.

At the moment if I want to put up a trade of, say, 50 Zebra Carcasses, I have to go down the list clicking each carcass one at a time, which is tedious and often means I lose count and there's no way to edit the trade once it's gone up.

This would be helped if we could put stacks on a trade using the same UI as Organisation (i.e. one list of items as individual items & one as stacks of each kind of item).
