// Wait for Summernote to initialize

    // Grab node tree from visual editor
    var masterNode = document.querySelector('#entry + .note-editor .note-editable');

    // Find CODEs and PREs

    // Apply changes to master copy in case of immediate save or switch to code view
    document.getElementById('entry').value = masterNode.innerHTML;
    // BUG: for some reason, this causes changes made in code view to be discarded if you don’t switch back to visual first, so let’s bring back our good old code view save fix...

        $(this).val(contents);
