This is an excellent addition to any forum and it's the first thing I add when installing a new style. I absolutely hate scrolling back up to the top of the page after making a post.
Although I just use the following code...
Code:
<!-- Extra Breadcrumb -->
<div align="left">
<span class="navbar">» <a href="$vboptions[forumhome].php?$session[sessionurl]">$vboptions[bbtitle]</a></span> $navbits[breadcrumb]
</div>
<br />
<!-- /Extra Breadcrumb -->
