I kind of like the idea, but I think it would quickly get pretty messy, trying 
to solve this in RKWard. This really seems like something that should be 
added in R itself. Something like an
	options ("default.par")
Where you could specify a list of those elements of par() that you want to use 
a different default, for. Somewhat similar to options ("par.ask.default"), 
except more general. Example:
	options (default.par=list(bg="light gray", las=2, fg="black", pch=19))
In a second step, we could add a GUI to set those defaults in RKWard.

I suggest posting to r-help about this first, to see, if there isn't some 
solution already hidden somewhere, and later to submit a wish, if there 
really is none.

Well, and the problem is that I don't really like this ;-). Or rather, more 
generally speaking, it is probably unlikely that we can find a default that 
is good for all. So the default would need to be configurable in some way. 
Therefore hard-coding it in the plot_options plugin, or whereever else is 
going to be difficult.

One thing that we could do some day (but not something too easy to implement), 
would be a generalization of the idea of having selectable "default settings" 
in plugins. Then we could also give the user a possibility to create an own 
set of defaults for a specific plugin, so at least inside that plugin, the 
options would already be set as desired. But that's only a partial solution, 
and not for the short term, either.
