Say if you're looking for a coin from a country, I believe there should a tool to minimize the search with a tool to find coins of the country which Numista members have it. Can help massively with Ancients coins since most of the Ancients Coins aren't for swap in the catalog. This help members without scrolling tons of pages to find a Numista with a coin for swap. (Yes I know there's a swap icon on a coin if it is available for swap, but I am looking if Numista members are looking for coins which fit a certain requirement, to easily click “available for swap” button and see which coins are available for swap.)
Example: Say if you wanted a Roman Empire Silver Coin of any kind to add to your collection, instead of scrolling through pages looking for the swap icon on the coin, you can easily click a button to easily separate the coins by if it is available to be swapped by Numista members.
