Dropbox v3.7 for iOS Adds Action Extension 

The #Dropbox for iOS users will now see the 'Save to Dropbox' feature under the sharing button of any app and can directly upload the files to their #Dropbox accounts in specific folders. If in case the users are not able to view the feature, they can simply open the share menu of a photo or a document that they want to save, scroll to right on the bottom row and tap on 'More' option to turn on the Dropbox Action Extension. Users can also reorder the extensions on the sharing list. The updated app is available to download from the App Store.
