Google now makes it easier to collaborate on translations with chat in “Translator Toolkit,” that lets you send instant messages to colleagues, friends, family and groups directly from within Translator Toolkit. Features & settings of chat are same, including going on record to save translation chats in Gmail. If you don’t want to be interrupted as you work on a translation, you can simply go invisible or turn off chat through Translator Toolkit settings. Also, you can now change your display language and set the toolkit tabs to open or close by default. And expanded the entries in dictionary tab, including useful information like parts of speech and alternate definitions. For e.g., if you're translating “cancer into Chinese,” you’ll find alternate translations for cancer as a disease and cancer as a quickly-spreading danger so you can find just the right word for your translation.
