Not for faint-hearted php coders ;-)
Ever wondered about Elgg's views
    => what they are
    => what can be extended ?? ;-)

ELGG:

var_dump ( $CONFIG->views )

EG:

PlugIn/ Theme extends a view :-

    function zextender_init() // Extend system CSS with our own styles
    {    extend_view('css','zextender/css');
        }

If we look at this Elgg $CONFIG->views var dumo I have done -
we can see exactly what all the vieware and how they are being extended
e.g. look at the "zextender/css" under "css"
