Google's Field Trip app may not be at the front of everyone's mind, but it's still being developed and improved. The latest update has added several new sources of information and added a new way to dismiss and snooze notifications that appear. You will now see more content from Art Nerd New York, Cultureist, Mad Girl Eats, Weekend Sherpa, Wilderness Press and more when searching for local info. There has also been a pretty big overhaul of the notification system of Field Trip. One of the complaints early on was Field Trip being a little too notification happy -- turning on your screen, talking and vibrating too often -- which made many people turn it off or uninstall it completely.
When you receive a notification on the lockscreen now, you'll have options similar to an alarm: swipe right to unlock, up to "snooze" (and not receive notifications for the rest of the day), and left to dismiss. There are also more configuration options for how you would like to be notified, letting you receive regular status bar notifications and keep Field Trip from waking the screen when they arrive.
There are a lot of major usability improvements in this update, so you may want to give it another try if the early issues pushed you away before. You can grab a download at the Play Store link above.
