I would like to see the lastname instead of the booking ID in the overview in the calendar. This would improve the usability a lot and would be very important for me.
Is this possible? Maybe with a little change in the plugin code?
By default, there is displayed a booking unique ID in Bookings > Calendar, and there is no possibility to display the last name instead. However, note that when hovering over ID, there is displayed more guest data (see this screenshot https://prnt.sc/tlollx).
