We have improved the marking of missing and owned series in the collection. Individual check marks no longer affect unrelated stamp parameters. For example, checking a stamped series for exchange will no longer change the missing and owned stamps. The only effect on the parameters lies in the premise that a stamp cannot be both missing and owned, due to the unambiguous marking of the stamp field with the appropriate color.
In addition, we have added the ability to mark an entire year this way. This follows the same principles as marking a series. The only difference is that the year can be on multiple pages, but the marking only applies to the part of the year shown.
We would be happy if you test the functionality and let us know how satisfied you are with it, or suggest any improvements.
