There is now an "integrations context" in the front-end which allows connections to be made to external third-party APIs.
A user settings window is added to edit the integrations for the current user.
The back-end stores secret data for the integration and proxies requests so that the front-end is able to use these APIs pseudo-directly.
The first example is the Spotify API using client credentials, which allows e.g. searching tracks and artists.
