It would be nice to have the possibilities to group the periodical issues on “my bookshelf” into the series. I mean, to show only one series of books or catalogues instead of 20 volumes separately, similar like it's in general with series of books in literature section (but this could be personel setting as other users would like the full list).
It would be also nice to have the possibility to export this to Excel, the same way as with coins/banknotes/tokens..
