This is one of two Google rumors that surfaced over the weekend. The other one is here.
Google has a weakness when it comes to keeping new products a secret. According to Garett Rogers, Google uses volunteers to do much of its foreign translation–they provide them when a sentence or two and the volunteers provide the translation. While Google gets all of their translation needs fullfilled for less than minimum-wage, it can make it hard to keep new products a secret.
Rogers first provided us with a screenshot that suggests a new interface for Gmail might be forthcoming.
Next, Rogers did some additional digging and found more translation screenshots that suggest one of Gmail’s new features will be the much-desired “offline” capability.
