because:

[...(  <- this is the "memory unit"

will only be saved in a (sub)patch. this can't live in an abstraction,
as hitting "save" on the main patch in fact does nothing to this "memory"

I don't want to name by abstractions like a.pd, b.pd, etc...
and nor I don't want to make 50px wide sliders.

if you don't get what I am talking about, please see
http://lists.puredata.info/pipermail/pd-list/2006-05/038312.html and

when I have more free time I'll make an external for doing this...
I can't believe pd can't have it's internal preset system.... MAX has
its (multiple)preset object, and almost all patcher dataflow software
have one... :|

maybe the pure-data API lacks functions for saving/restoring state of
*ANY* external (if the externals needs/wants this)?
