[Feature Request] placeholder for inventory slot items

[vajuvung]

so my request is adding placeholder for intentory slot. Why i dont use other placeholders?(i trying) well... when you use wand with inventory mode placeholder do not work because you have spell inventory, not real inventory.

okey so for example i can write %magic_slot_% and i will get name of item. %magic_slot_1% and i get sand because i have sand in my 1 slot.

oh and also from off-topic. Maybe put pay version plugin for a little support for yourself. This is only suggestion plz don't angry at me
