-- while we're still at brainstorming, I'll toss in a further thought
in this category: Turn the "Preview"-checkbox itself into a tri-state
control, e.g. a drop-down menu "Preview disabled", "Docked Preview",
"Separate window". (Actually it would even be possible, right now, to
have two separate <preview>-boxes, one for docked, one for "default"
placement. I don't think it's what we want, though.)

Hm, yes, still needs attention, but as you say, it probably does not
really relate to the preview issues.

Good idea in principle, but I'm afraid this would be more complex:
First off: recordPlot() is the function you were looking for, and its
help page cautions that only plots from the current session can be
replayed (which could still be helpful, of course). I'm also not sure,
if it would work with lattice plots and such. (Certainly possible in
principle: Our plot history feature uses this, but it also has quite a
bunch of rather complex code for this...)

Follow-up question (not terribly important at this point) will be: Does
it also "detach" the preview in the sense that the preview is no longer
updated by the plugin?

Hm, we may be on to something, here: perhaps the "problem" of a docked
preview simply boils down to the missing menubar. I'm not entirely sure
it will be possible to add, but I can look into this. We _will_ run
into some sort of platform issues, though: Think of top-of-the-screen
menus on Mac, for instance. Alternatively perhaps some "menu in a
popup" like is fashionable in browsers, these days.

Considering it's a Mac-only thing (and in fact a Mac-binary-only thing),
I'd suggest calling it 0.6.4-1 like most distros would do for a new
revision of the packaging.
