You can specify a set of elements that can be hidden. This is achieved by
passing the hide query parameter and specifying a comma-separated list of
items. Currently only mini (to hide the mini player launch button), notif
(to hide the lock screen and notification control settings), launchPlayer (to
hide the launch player setting), and scale (to hide option for larger
elements) may be specified. e.g.
http://<yourserver>:9000/material/?hide=mini,notif
This query parameter is only intended to be used by applications wishing to embed Material such as the Material Skin android app.
