Every feature is a plugin, grouped by what it does.
A Burton feature is a plugin: client routes and navigation, plus an optional HTTP API. The shell does not change when you add one. Enable, disable, and reorder in Settings → Plugins. Disabled plugins leave their data in place; routes and APIs return not found.
Docs on this site group plugins by function (create, publish, configure, manage, communicate). The in-app sidebar uses different headings (people, communications, content, finance, documents, system).
Postgres logical-replication publications are declared per server plugin so Rabun can subscribe. See Rabun ETL.
