The Pages and Documents panel provides a convenient way to:

  • Navigate to any page in a document in the Pages panel.

  • Select another document to view from the multiple Documents panel.

  • Create a new document by dragging and dropping pages from another document.

However, this convenience does have a price. VirtualViewer HTML5 for Java performance degrades because it is processing every page in the document Pages panel and/or the first page of every document in the Documents panel. If you want to speed up performance, you may want to disable or hide the Pages and Documents panel by setting the showThumbnailPanel parameter to false in the config.js file as shown in the example below:

var showThumbnailPanel = false;
