The ADIF History file uploaded into PoLo contains all QSOs that were exported from my main logger, jLog. Because I also use PoLo for working DX, it would be great to have PoLo display an alert when I enter a callsign that is to a country that I have never worked. The counties that I have already worked are in the ADIF History file so PoLo should be able to determine that an entered callsign is to a country that I have not yet worked. This would be a very nice feature addition. Thanks!
