Now it is possible to "star" reservations in order to highlight certain ones. When a star has been added, the star will appear next to the guest's name on the internal reservation calendar.
To add a star, simply click the star at the top of the Reservation Details screen.
We think there is room for expansion of this feature, and likely will be adding to it over time. Some suggestions we have already received include ability to set symbols other than a star, filter by starred reservations, and automatically star reservations that have items for sale attached. If you have any additional suggestions, feel free to pass them along.
