I have fixed most of the issues that you had reported earlier. 

I have added two new features:

1. Attaching Custom Styles to the document
   - See http://permalink.gmane.org/gmane.emacs.orgmode/40026

2. TOC and Outline numbering are done natively. i.e.,
   Tools->Update->Update All would update TOC index automagically. (This
   wasn't the case with earlier exporter)

Currently syntax highlighting is done using htmlize. This package is not
part of Emacs proper and has to be installed separately. Since my setup
instructions doesn't include htmlize as part of load path, HTML source
blocks are uncolored.

As for ODT, fonitification support is missing. I can probably take it up
once my sources gets in to Orgmode proper.

As a side-note, I wonder htmlize was preferred over htmlfontify for
fontification of source blocks. The latter package is part of Emacs
proper. One advantage of using htmlfontify is that fontification can
work out of the box.

May be if you can share your config for OrgVerse I can include it in the
default styles file.

I have fixed issues with LaTeX: verbatim.

In the master branch, the html exporter doesn't seem to be terminating
each line of \begin{equation} ... \end{equation} with <br/>. I see your
POV that including of line breaks will make the output pretty. For now I
have retained the existing behaviour of HTML exporter.

I have fixed this.

References in Orgmode file are currently coded like this
"\ref{fig:1024}". Note that this is of the form "category:value" where
category could be one (or any) of Chart, Figure etc and value is the
sequential value.

In the example above (which if from my test.org file) you will see that
Fig appears in caption and all Fig stuff is sequentially numbered once
the Document is updated with Tools->Update->Update All.

Note: For sake of completeness one can declare "Fig" as sequential
variable in content.xml as is done for "Illustrations".

--8<---------------cut here---------------start------------->8---
<text:sequence-decl text:display-outline-level=\"0\" 
--8<---------------cut here---------------end--------------->8---

This is done as part of `org-odt-begin-office-body'.

The caption now has a Colon separator.

Tools->Update->Update All (OpenOffice.org) will make sure that all
references to Tables and Images are 'correct'. Yes, this needs to be
mentioned in the manual.

Doest his problem still exists with the new odt exporter. Can you send
me a sample .org file and the generated .odt file.
