why does this go into a new settings-box?  doesn't that add a border?  that's
not what we want, no?

[stevenjb, 2016/11/30 22:58:19]

Only one or the other will be shown. Also, 'first' or 'continuation' hides the
border. I'll use 'continuation for both of these to match 'Allow shared
proxies'.

[Dan Beam, 2016/11/29 05:25:34]

arguable nit: use dom-if instead of hidden binding

[stevenjb, 2016/11/30 22:58:19]

Done.
