Google has functionality to display "Holidays" calendar, while in LN Client you do need to find way to import holidays (eg. proper/uptodate Domino server with enabled/accessible functionlity).
In case of global companies, it would be very useful to get Domino server running with all uptodate and available holidays for import (or some other way).
Both for Verse (oncloud/onprem) and LN Client.
