To address the usability issue we found early on (that new users don't think to create a booking by dragging in the calendar) we've added a couple of tips which appear on screen to users who have not yet created a booking.
Once you've created a booking once, the tips don't appear again, so they don't get annoying (which, let's face, 99% of "tips" are an annoying distraction).
Here they are in this video:
We've also changed how the days are displayed in the calendar. Before, all days were coloured the same, so if a view included days from two consecutive months it was sometimes unclear which days belonged to which month:
Now it looks like this:
The days from the previous month are greyed out, and use the same background as the tabs for unselected months, so much clearer which days are August and which are September in this example.
