So i have played with the settings a bit, but i've come to one problem when using this on servers with currencies in item form (e.g. emeralds). They've made it so, that the lore of the item says how much the entire stack is worth. If i then add another emerald to the stack, the mod says:

- previous amount
+ previous amount + added amount

Maybe a feature, that would allow you to set the counter by id (minecraft:emerald) would be a nice thing. :)

I'm not sure I understand what you are asking. You say that, in this server, the stack's name contains your balance?
Like 20x[Emerald (300 coins)] ?

If you can show me a visual example I may be able to understand better.

That said, what you ask seems a bit too niche for me to implement... Too easily broken when different servers use different formatting styles, or even when you change your minecraft language...
