You can select the number of shown QSOs from the popup menu on the right hand side. Take caution when selecting All QSOs. You may notice a short delay while starting when you have more than 20.000 QSOs in the log.
Sort the log by clicking in the table header and adjust the width or reorder the columns using the mouse. There is a contextual menu provided in the header to hide/show columns.
When you select a row, the DXCC Info Box and the Station info Box will be updated. A double click opens the QSO editor, the same as Menu–>Logbook–>Edit.
A magenta text row indicates an invalid operation.
