1) Could you not use the hook forum_view_pagenav_before and str_replace the HTML?
2) If I assign a moderator to a category, this modification doesn't show moderators in child forums. It's because the content condition ('content' => array('node', $hookParams['thread/forum']['node_id'])) only checks if that specific ID has any moderators and doesn't check for inheritance from parent nodes.
Change mein to main in the options tab, a simple spelling mistake but figured I would let you know before someone bashes you for it.
You should move the "botton" display for threads down further, where it stands right now it interferes with possible bars on the bottom of posts. I think if you moved it down to the very botton of the page below the reply box where post reply, upload a file, etc are. Just right below that would probably look a lot better.
I also suggest for the thread view the one of the top you put a little bit higher up. While this will not affect most forums or their functionality, if you have a thread that is unapproved or locked you have a bar that goes above the actual thread. Which conflicts with the placement of your actual add-on.
This one seems like more of a bug then personal preference, but when I added it for my forum view on the top, it ended up going in front of our "Post Thread" button on the default skin, not even our own skin. Which makes it a little hard for users to post threads when they can't click the button.
Now while I know some of there are simple alignment issues that can be quickly fixed, just thought I would bring them to your attention for future releases and improvements. Great add-on otherwise and I look forward to your future versions. I've attached screenshots of each problem to help you get a better idea of what I am talking about.
Small Update to Beta 2 for Node View. They changed the hook. You must change it back inside your template.
If you want to display the Moderators inside the Nodes, please do step 5 form installation. If you styled your own view, backup them before you install the XML. But it is not neccesary. The XML only fix typos and the CSS to not diplay the mods in front of the buttons.
