Hi Tobias, i deal with prices in R$ (Brasil) based on U$ (Dolar), this prices changes every week (at least). A option to view my table prices in determined date will save A LOT of time.
For now, i have to create a new .xlsx table for every price change, than i keep a folder with the name of the product and the related .xlsx named with the current date. I work with thousands of products and each one have six different prices. Can you realize how much time i will save with the ability to compare old versions? Keep it on the ideas list for the next version of the plugin.
Thank you so much for developing and supporting TablePress.
