Inbox by Gmail's getting a few new features today, including integration with Trello, GitHub and a new Google Alerts section. Trello and GitHub updates work just as you'd expect. Both show you a summary of updates sent from both apps so you can easily keep on top of things without actually leaving your email app. Google Alerts will also be summarised for you, allowing you to tap on anything of interest to read more about it. Aside from the new summaries, you can also now insert Google Drive links into emails and drag-and-drop contacts between different fields.
