When we trade, we have the opportunity to send 400 items, that i think could be raised to 1000...
and another thing is that we have to use these smal arrows again, and im over the 40 now, so the eyesight not so great anymore
My suggestions is :
A Max of 1000 items
The opportunity of writing the numbers instedd, i know it can be done by writing it with the max of 1000 also
