Sustain user input in master

Hi Rolf,

You can use the following function to hide all objects whose names start with a prefix in the current slide (including the master layout):

function hideChildObjects(parent, prefix) {
    var children = parent.children;
    for (var child of children) {
        if (child.name().startsWith(prefix))
            child.hide();
        else
            hideChildObjects(child, prefix);
    }
}

//e.g.
hideChildObjects(prez.slide, 'NavLeft_');

Regards
