Is it currently possible to build an app or script such that it appears as part of the Gmail interface and can interact with Gmail message content?
For a while Gmail sidebar gadgets allowed the creation of customized sidebars that would appear in the Gmail interface, but these gadgets are now deprecated.

Gmail add-ons provide a way of extending Gmail, using Google Apps Script as a platform.
You can create a UI panel using the widget elements provided by the Apps Script Card service. The interfaces developed for Gmail add-ons work for both desktop and Android devices.
Gmail add-ons can react to Gmail message content and also use the other Apps Script services (such as the Calendar service) to access data on behalf of the user. Connections to third-party services are also possible.
