    Not bad! I couldn't find a delphi component called MultiView, but the word
    itself is used a lot, and so are PolyView, FreeView, FlexiView and similar
    variants I've thought about.

    Have you seen the demo app? (Asking only because if you have seen it and
    the purpose is still unclear, then I have a big problem :)

    Yes, quite. The component itself doesn't know about any particular object,
    but the idea is to display object properties such as you describe. I would
    create a class named, say, MultiViewController which would manage the
    component and know the objects whose properties are displayed, so that the
    layout and all the details can be encapsulated. (I'm using this technique
    with VirtualTreeview, so as to avoid code duplication and littering the
    form's unit with all the events necessary to drive the tree.)

    No, it doesn't, and it's not data aware. I'd like to add in-place editors
    eventually, but at the moment it's only for presentation.
