+Hiding tables
+-------------
+
+You can hide tables from the database listing view (in the same way that FTS and
+Spatialite tables are automatically hidden) using ``"hidden": true``::
+
+    {
+        "databases": {
+            "database1": {
+                "tables": {
+                    "example_table": {
+                        "hidden": true
+                    }
+                }
+            }
+        }
