Lately, I've upgraded it to also support booking rooms by querying for free rooms and "fast booking" them depending on a custom priority list. I have a personal use case for this one: even periodic meetings don't have assigned rooms, so I can just bulk-book the first available rooms for the next couple of weeks for every meeting that does not have an associated one.
I hope this app can help others find some help for their corporate lives, as it did for me :D
