Gmail Contextual Gadgets

Gmail contextual gadgets, previously in developer preview, are now available to all developers. These gadgets allow developers to embed interactive content and functionality directly within Gmail, enhancing user workflows by providing contextual information and actions alongside emails. This enables richer integrations with third-party services and applications, allowing users to manage tasks, view data, and perform actions without leaving their inbox. This post introduces compose-time functions for add-ons, allowing them to provide dynamic content and suggestions during email composition.
