I have used this patch:
http://dougal.gunters.org/blog/2005/01/17/improved-thunderbird-opml

and it works ok but it has the following flaws:

1. It does not save the user's folder structure (feature?). I have created
several folders under "News & Blogs" and add a new feed under appropriate folder
(category). I also often rename the feed to be more informative (e.g. "Alex" is
not very informative). Using export functionality of the patch, I lose all my
folder settings and new names given to the feeds.

2. If I import an exported feed file, all feeds are added to the root (News &
Blogs) although I might already have the same feeds under subfolders. Importing
should check based on the feed URL if the feed already exists.

Adds OPML export. Folder groups are preserved.

Attachment: OPML Export

the previous patch had a little mistake that broke the display of the feed
title

Very nice effort. If it's not too much asking, it would be optimal if it could
export one's folder structure (instead of restoring one folder per feed), and
the "show the article summary instead of loading the web page" checkbox state.

Hmm. I think it does export folder structure rather than one folder per feed. It's just that Thunderbird 
imports them differently. As for the summary/webpage state, I don't think OPML supports that.

I noticed that the resulting OPML file is one big line. Is that expected /
normal or should things be broken up into multiple lines. I'm guessing that's
probably a result of the serializer and not this patch per say?

The one UI thing I don't like  about this (not specific to this bug) is the
bottom of the subscriptions dialog is getting really busy as we now have 5
buttons across the bottom. 

I may play around with moving Add / Edit / Remove into a vertical box to the
right of the feed list box, leaving import and export as the lone horizontal
buttons on the bottom. 

In any case, I can decide that later so I've gone ahead and checked this patch
in. I made some minor changes to the formatting of some braces around if clauses
otherwise...great stuff!
