In case archives are often compared to each other, one can easily find the same picture pairs again and again. This is of course not wanted and thats why one can add those pairs to an ignore list. Such picture pairs, ones added, are no longer presented as results.
Via Ignore List / Edit all picture pairs are displayed in the result list. Excluded are those pairs where not both parts exists. In the list entries can be deleted or be added to the now empty background list (not visible). On dialog change one will be asked which of the lists should remain.
