If its not too much coding, it would be awesome if there was a drop down menu, for if your CoDing an item to somone and your on a mobile device you can send them the amount of items you need to, and not too many. I constantly run into the problem of not being able to split stacks, because the only devices I can access Sylestia on is my tablet or my phone,and its a real pain to work out a trade with somone when theres a stack of whatever item you have, and both of you are on mobile devices. It would be awesome to have if its not too much trouble!
If there's anything you find could improve/dislike this idea, id love to hear it :3
