I collect cards in both English and Japanese, and I often compare prices between the two to buy whichever is cheaper. This might be a fairly personal use case, so not sure how common it is, but wanted to put it out there.
I really like the recent addition that lets you switch a selected card to its Japanese version to compare prices, that's been really useful. It would be great to take that a step further and show both prices side by side on the card details, instead of having to switch back and forth.
It would also be awesome if this applied to the scan feature too, when scanning a card, showing both the English and Japanese price at the same time, instead of having to look each one up separately afterward.
