This is really a killer of a change. I been on many workshop meetings with Airbnb since July and been pushing to bring the at-a-glance feature back that for some strange reason it was taken out.
There is also the added feature of allowing color to be added to a range of dates (or even script), as this visual feature would convey so much information especially for many hosts. In our case there are 8 different hosting combinations that with the ability to add color, it would communicate (at-a-glance) much information. I.e. the source of the booking (if Direct or VRBO by example), also usable by support personnel (cook, fishing guide, driver, etc), checking time (regular or latish), etc etc.
It is basic stuff that in all walks of life visual organization is the most powerful; i.e. who wants to gather information from a book that forces one to 'cross-reference' a relevant chart for example many pages away.
Airbnb will do better to always listen- comprehend-and believe (the 3 imperative steps to learning) those from the 'outside' world.
