Search within your modules/features for .po files and import them in the DB within the right text group.
When you install a new modules with translations, the Locale module automatically import them in the "Built-in interface" text group and choose the mode "Existing strings and the plural format are kept, only new strings are added.". It's ok for mostly all modules but not for Features that can contain Content types, Fields or Views.
This module recognize the system name of the text group in the name of your .po file and import it to the right text group automatically.
The .po files will be searched in an "auto_transaltions" folder within your modules/features instead of "translations". sites/your_site/modules/your_module/auto_translations
Google Cloud Storage allows you to replace the local file system with Google Storage. Files uploaded into Drupal will still be managed by Drupal, but instead of being stored on the local server, files will be stored in Google Cloud Storage.
