URL given above points to Petr Pisl's reply to a mail I had written to the <users@php.netbeans.org> in September during
NetCAT 6.5, just before Code Freeze... Here's a part of the mail I had sent;
------------------------
AFAIK, there's a really cool feature, which I think might have already been
discussed on this mailing list, when you invoke CC inside include, require!

What it does, instead of showing list of items in CC window, it shows one
item named as "Browse.." which is an action, and clicking it pop out a file
browser which shows only the current php project's files view. One can then
select the relevant file, and make it relative/absolute depending on the
choice made.. before clicking OK.

How about this enhancement in the current support?

Also, as you know, we get Code completion inside 2 double quotes, like

align="cursor"

at the position of cursor, invoke CC and you get options in the context of
alignment.. Now, tell me one thing, whether its a feature of HTML editor
support, or PHP?

If its done by PHP editor support, then how about extending this
functionality elsewhere too, when we write src="" and href=""

Thanks!
