I disagree. I was grately impressed by preview-latex when I tried it
(around 2 years ago), so much so that I even considered moving to emacs
from vim. It is extremely useful for mathematics and images: you can see
the typeset result rather than a bunch of code. This means that you can
proofread in the editor rather than a pdf (or dvi) reader.
What is needed for an improved support of preview-latex in context? Last
time I looked into preview.sty, I could not understand how it works. If I
were to do the same thing, this is how I would do it.
Run context with a custom module, which writes the content of each
\startformula <formula> \stopformula into a temporary file as
\startTEXpage \startformula <formula> \stopformula \stopTEXpage. Lilypond
and gnuplot modules already do something similar. Then process the
temporary tex file. You will get a pdf file with one formula on each page.
Convert each page into png, and use some lisp magic to insert the image at
appropriate places in the buffer. Obviously I am missing a lot of things.
But, am I correct in assuming that from the context end, the problem is
