Switch off / on domains

domain always shows small on/off button in bottom LHS
when you hit 'off', you immediately go to a static HTML page saying 'this site is switched off'
every time you then try to access that domain, you redirect immediately to that static HTML page
to switch site back 'on', there is a slider on the static HTML page. slider design is such that user must click the slider circle and drag it all the way to the right-hand-side in order to switch the site back on
should be possible for this entire feature to be switched on / off via Nudge options
should be possible for certain domains to be always 'off' by default when you start a new Chrome session
