+Subject: [PATCH] Provide the org.gnome.Settings launch-panel interface
+
+GNOME applications such as gnome-calendar, gnome-contacts or evolution
+open the online accounts settings by activating the "launch-panel"
+action of org.gnome.Settings on the session bus, which is only provided
+by gnome-control-center. On desktops that ship gnome-online-accounts-gtk
+instead, these buttons silently do nothing.
+
+Export the application actions on /org/gnome/Settings as well, own the
+org.gnome.Settings name once the application has started and install a
+D-Bus service file so the application gets activated on demand. The
+"online-accounts" panel presents the main window; when an account id is
+passed as the first argument, the matching account is opened, mirroring
+the behaviour of the gnome-control-center panel. Other panel ids are
+ignored with a warning.
