Nice challenge, nice work; but wouldn't it have been simpler (& easier) to leave the switch button as an icon on the toolbar and have it flash for instance when applicable? That would prevent any issue on pages ...

Yes it is. But this is simpler (& easier) for user and that a point. Issues on some pages i always try to fix, when users tell it to me. Thank you for feedback.
