as i said above, in another reply just now, i'm aiming at a "sweet-spot" that _might_ be as nonexistent as you say, i.e., an "average" user who'll edit a few lines of .html.

ideally, s/he should have a good understanding of all the implications and ramifications of those edited lines, too.

all of which should take no more than 3 minutes, total, because that's all the average person will devote to it.

meaning it will boil down to calling a javascript file, plus jquery (or some other package), and _nothing_more._

if it's that simple, this kind of "supercharging" will be used by enough people that it could attain critical mass.

otherwise, not.

and i'm quite sure that, if you actually do the exercise, you'll find that none of the solutions mentioned can be installed in such a straightforward and trouble-free way.

surely not in 3 minutes.

nor with any comprehension of all possible ramifications.

it might be that they haven't been packaged up that way; or it might be that they are complex enough that it won't be _possible_ to "package them up" to be that simple; but -- either way -- they are not now the answer i'm seeking.

i hope this clears up my position. thanks for the dialog.
