Improve swap page to also select coins not in your swaplist yet and select collection

More and more often the people wanting to swap don't have any coins that interest me for my collection. Sometimes they want coins I have a lot of and we can do a swap for coins I don't yet have in my swaplist. Like that we still both profit.

Would it be possible to add a button on the exchange pages "I don't have this cointype in my swaplist" to make it easier to find them?

Additionally it might also be useful to select different collections on this page to check coins against, as one sometimes has overlapping collections and might need a coin in both collections. (eg. I already have a Greek Drachme in my Europe collection, but I'm still missing this owl it in my nature collection)

Let me bump this suggestion, to be able to select "cointypes I don't have in my swaplist".

The options for swaps have already improved greatly, but there is always room for improvement.

Thanx Xavier!

Bump again for 2021 ... already 3 people are fan of this suggestion

Another extra 4 likes, time for a spring bump ... happy swapping to all

Let me revive this suggestion … doesn't yet seem to be on the radar for development :-(
