This is a PHP class that allows you to easily create self-recovering panels. Panel is a component of overlapping "group of panels", similar to the sidebar of Mozilla or Microsoft Outlook. The main part of the overlapping and navigation is done in DHTML, and includes a PHP class to facilitate the creation of the panel side server. Panel content can be either an external page or given as a string. Basic customization (colors, fonts, etc.) is possible via method calls. Further customization can be achieved via a CSS. Documentation is only in French at the moment.
