I have a feature request, which might be also interesting for others.
So I am working on a little app where I can track the prices of my collection, and on how much the cards gained or lost in price.
I have to maintain a second csv file where I have inserted two more columns and maintain the date I purchased a card and the price I paid for that card. I then misuse another column to mark the cards that I have listed in my second csv file. So I can very easily see in my app track the prices.
Is there a possibility to add those two columns?
