Hey all,
I can see this is in an advanced stadium already. Maybe this comment can still be considered.
I am quite confident that the international notation for units like this is x/y, like km/h (kilometers per hour), N/m² (Newton per square meter = pressure), V/A (Volts per Ampère = Watt (Power)). So the same accounts for price per unit (€/item, $/100 g, …).
To comply with this standard and make this wonderful new feature look “even nicer” I am recommending to drop the blank spaces before and after the slash /.
Does anyone agree?
Thank you for reading!
