+sticky_controlbox
+-----------------
+
+* Default: ``false``
+
+If set to ``true``, the control box (which includes the login, registration,
+contacts and rooms tabs) will not be closeable. It won't have a close button at
+all.
+
+The idea behind this setting is to provide a better experience on mobile
+devices when the intent is to use converse.js as a web app. In this case
+it doesn't make sense to close the control box, as there's often then nothing
+"behind" it that's relevant to the user.
