Hi Al,
Responding just to the structural question for now. I think I
miscommunicated:

> buframe's.
I wasn't proposing to change what's displayed *by default* for all
previews, but rather what's shown *after entering an existing preview*.
The options would include:
- just the construction symbol and the tex code (default behavior in
AUCTeX)
- the preview before the tex code (current behavior of
preview-leave-open-previews-visible t)
- the preview after the tex code
- a buframe showing the preview
Does that clarify? Could either shoehorn this option into
preview-leave-open-previews-visible, or absorb that into a new defcustom
('preview-reveal-display'?) taking the values 'none, 'after, 'before,
'buframe. The issue is orthogonal to preview-point vs. normal -- it's
just about "reveal behavior on entry". Note that we're not trying to
edit inside the preview image - we're just choosing how the preview is
displayed when the tex source is made visible after you enter the
overlay.
Does that clarify? I think this would be useful (e.g., I would try it
out with traditional previews).
Paul
