I have three open inventory slots. I have over two full pages of trades, most of a single sun token, from fighting named. I have a nice hefty existing stack of sun tokens. You'd think, oh, those forty or so tokens would just add onto the stack that already exists, right?
Nope. I have to manually stack them. Three at a time.

Accept trades. Stack.
Accept trades. Stack.
Accept trades. Stack.
Accept trades. Stack.

SO MANY TIMES.

Please, please do something to make this process less tedious. Stacking things, to be specific. There is absolutely no reason that A) those tokens need to be in forty individual trades to begin with, or B) that they shouldn't all be compiled with the existing stack. It just adds unnecessary tedium when I should be breeding my sylvorpas or finding cheap avatar items.

If you're concerned about people saying 'oh, I never got my trade' make it a toggle option in settings! Require a verification, "Understand that turning on auto-stack means you may not notice you've received additional items to existing stacks" if it's that much of a problem. But please, this is just ridiculous.

I don't have this issue yet. (YET.) But I agree. I've seen so many games with bad stacking systems like this, and it always makes me want to rip my hair out.
