The booking calendar colored ribbon currently shows the guest name and number of guests in parenthesis. Can I suggest you also include on the ribbon:
The listing site it came from.
A hyperlink to the reservation on the listing site.
A hyperlink to email the guest.
A "fully paid" indicator.
Obviously this would get crowded, so you'd probably have to make it user-configurable
Yes, we've been seeing more requests to make the calendar stripe configurable. That's probably something you'll see eventually.
