Here Here! Toby for PM
Also on the unrelated vertical patch aligning issue I think aligning
lines and arrows the way most graphics apps and iWork suite do it
would be preferable to any menu command based system.

Global Variables / "Preferences Patch"
Originator: operator Modify My Radar
Number: rdar://8249719 Date Originated: 29-Jul-2010 10:19 AM
Status: Open Resolved:
Product: Developer Tools Product Version: 10.6
Classification: Reproducible: Always
Quartz Composer has no way of having global variables or preference
parameters, short of patching every instance of their need back to
root. Not only is this extremely tedious, it breaks on the slightest
re-jig of the patch.
A common example in my use are common font sizes, colour palettes,
grid dimensions.
You could implement as a 'send receive' pair where the object sent
is a constant, set in the settings panel. You could implement a true
'send receive' pair, but evaluation of the graph would get
interesting.
Alternatively, a patch that can be duplicated throughout a comp,
that has output ports with values that are shared across all
instances of the patch in that comp.

They're all "valid", it'd just get dup'd (if you're going to make
an intentional dup, at least include the original radar URL so it's
easy for the screener to tie them together without working too
hard :)
also glad to see the buffer / hold last value idea isn't bunk.
I mentioned that in my reply to Keith:

The more fundamental problem is execution order -- if a
broadcaster is layer 2, and a consumer that uses it is layer 1, it
will always operate on 1-frame stale data (which could be wrong,
and isn't entirely obvious).
"1-frame stale" ~= sample&hold -- that's what spooky does today;
it works, but it can cause subtle problems (i.e. if you're passing
around images for filtering, some could filter the current frame,
and others the previous frame, and then compositing them together
can be weird -- this can also be used for artistic effect, of
course :)
