It often happens that coins are selected into swaps that later are not wanted anymore for whatever reason.
This can be simple change of mind, non availability, too bad condition, too expensive, etc.
Today - at least to my knowledge - there is no way to delete it out of the swap again which may create confusion
and a lack of overview.
Maybe this has been discussed before, if so I do apologize, but it makes sense to implement a delete function
for coins to be removed again.
