Hello

I really enjoy the org-preview-latex-fragment function,


    - However, sometimes I make typos and then
      org-preview-latex-fragment fails naturally. There is no
      error-log buffer which would inform me about the error I
      made. Could that be added?

    -  For some reason if I type

Test
$$\int$$
there is less vertical space (when displayed in thunderbird say) between the text and the formula
than
Test
\begin{displaymath}
\int
\end{displaymath}

Why?

Thanks 

Uwe Brauer
