Hello everyone,
My work requires me to use libreoffice. I have several questions using
org mode with libreoffice.

1 How to remove colon seperator in figure caption in odt files
exported from org mode?
2 How to change equation numbering to latex style, like e=mc2
(Equation 1-1)
I am trying to get equation numbers aligned to the right, with section
number before equaiton number in that section, such as 1-1, 1-2, 2-1
... Just like the libreoffice TexMaths extension. Is there a way to
number the png images of the converted equations. The following is an
excerpt from my file:
#+OPTIONS: AUTHOR:nil toc:nil tex:imagemagick
#+name: eq:sinh
#+begin_equation
\begin{equation*}
\label{eq:sinh}
\dot{\epsilon}=AFexp[-Q/(RT)]
\end{equation*}
#+end_equation
Thank you so much!
