WebMDI is a PHP class that allows the building of windowless MDI-type sub-windows.
Think about your favourite word processor (No, not THAT one ;) ). It has a main window that
houses its menu system. Each file you edit is contained in its own little window, that can
be maximised, minimised, closed, etc.
Q: Where did you get your web design skills from?
A: Skill? What's that?
