Greetings Numista and team,
There was a recent implementation of how you could see what swaps a selected coin was in. However, if I am not wrong, this can only be seen in the swap monitor. My proposal is to see the swaps the coin is in directly on the coin page. This prevents initiating new swaps just to find out the coin was already selected in another pending swap.
I just noticed that if you open a swap list of any user it will show you an icon similar to an envelope... that tells you that you have add that coin in another swap (and actually tell you in which swap by username).
Is this what you where looking after? or you mean in the main country page without even going to a swap list?
