Auto Grouping
From TibiaAuto Wiki
It will group all groupable items. TA can tell if an object is groupable by its entry in the tibiaauto-tiles.xml file.
It will collect all items of the same kind into groups of hundreds, but will not move items between containers.
It's easy to use. Just click it to enable it, click it again to disable it.
This module is deprecated since Tibia groups items now automatically for itself!
