Book something on the web, get it in Maps
A Google Maps update has recently been rolled out which provides quick access to flight, hotel, and restaurant reservations you've made that are linked to your Google account. These should show up in your search history on mobile, but for now the feature is only available in the U.S. and in English. There have also been a few UI tweaks to get you to navigation and traffic overviews more quickly.
The Google Maps update for the web also includes some cool stuff, like multiple stops when planning driving routes, and search results for upcoming events nearby. With any luck, these features will pop up on Android soon enough.
