You wrote that I can customize the layout view in custom layouts. (there number 3 I guess "Detail der Listenreihe"

but can I categorize here the evnts in months?
Is it not better to work with the menu type "View of one year" for here we have already the categorisation in months, just I have to change the range!!!, means it should not stop on 31st of December.
