Hi All,

I have been using org-mode and emacs for lectures in an engineering course.
I often have equations, and then source blocks that implement them. I can
display the latex fragments, but when I try to run the source blocks, I
have to type C-c C-c twice, because the first one removes the overlays, and
the second one runs the block. that is pretty inconvenient, because then I
have to put the overlays back on.

It looks like this is hard-coded in org-ctrl-c-ctrl-c in line 20358 of
org.el:

    (org-remove-latex-fragment-image-overlays)

What do you think of creating another customizable variable to control
this, with a default value to preserve the current behavior. then we could
do this:

(when org-remove-latex-fragment-image-overlays-CcCc-p
  (org-remove-latex-fragment-image-overlays))

Then, I could keep the equations up, and run and modify code blocks in
class!
