Just a quick question: does the software have filtering functionality? I mean, can it filter out duplicate log entries to make batch adding, deleting, viewing, and modifying easier? Because sometimes when I import logs, they become duplicated, and it's really frustrating when I have to manually sort through thousands of QSOs. Currently, importing a log file with 1000 QSOs results in 2000 QSOs after the second import, but only the first import contains the actual 1000 QSOs.
