Collapsable functions and classes like in Visual Studioand Komodo 3.1

[wyrmhaven]

when writing lengthy php or javascript scripts it would be very helpfull if the
coder could collapse the functions so that all you see is the function name and
it's arguments. then when you need to see the code in the function you click a
plus sign or other icon next to the function name and it expands the code so
that you can see the guts. I know that you can extend dreamweaver to maybe do
this.

what i need assistance with is either doing this myself or finding an
extension that already does.
