Great to see NOTAM area on printed map! But to find out which NOTAM is this, you need to read NOTAM texts on different page(s). If there are many of them, it becomes complicated.

I understand there is a limited space on the map to see all heading of NOTAM, but it would be nice to see at least some identifier, for example number which would correspond to a number in the list of text NOTAMs.

I agree this would be very nice to have. I'm not sure technically how we would do it, as overlapping NOTAM would cause a label-alignment problem and the chart printing system is currently totally separate from the NOTAM briefing system.
