[Orgmode] Combination of 'ordered' property and 'scheduled' hides TODO items.

[mrb]

Hi,

I'm using the ORDERED property in some/most of my projects and
generally hide BLOCKED items everywhere except in a special list of
blocked items which I review with some regularity. Overall, this works
fine, org nicely filters out what is possible to work on and hides
others.

I'd like to make  it a bit smarter by having scheduled and deadlined
items be 'unhidden' even though they would be invisible according to
their order.

A typical structure to which the above would apply is something like
this:

* PROJ Some project with sequential tasks
:PROPERTIES:
:ORDERED: t
:END:
** TODO First
** TODO Second, but scheduled
SCHEDULED: <2010-03-30 Tue>
** TODO Third, but deadlined
DEADLINE: <2010-03-29 Mon>
** TODO Last

In my lists the 'Second, but scheduled' and 'Third, but deadlined' do
not appear, because they are blocked by 'First'.

For the above situations, I'd like to make an exception in the hiding,
but do not know where to start. I could imagine a customization
variable which allows a list of exceptions to the 'hide' rule. 

Anyone has any tips/pointers on the above? 

Thx,
marcel
