Obviously with the introduction of clothing and other equipment that can be changed while playing it would be nice to have a level of control over the changing of equipment without having to resort to seriously inefficient methods.

Something like "HandleEquipment" that returns "[unit, current classname, previous classname, slot]" whenever clothing or equipment is changed. The classname can return "None" if the slot is empty.

This would add the ability for developers to control what players can use what clothes and equipment and where they can equip/remove them as well.
