refinery bread_crumb

I just made a breadcrumb for my site and put it in _content_page.html:
<% unless @page.home? %>
        <ul id="breadcrumb">
                <li><%= link_to "Home", root_url(:only_path => true) %> &gt; </li>
                <% [@page.ancestors, @page].flatten.collect do |p| %>
                        <li><%= link_to p.title, p.url %> <%= "&gt;".html_safe unless p.id
== @page.id  %></li>
                <% end %>
        </ul>
<% end %>
I'm wondering: Is there a better way to do this?
And, If I wanted to make this more reusable and add a page option in
the backend (Display Breadcrumb Yes/No) what would be the best
approach? Create a plugin?
Lastly, I'm falling in love with this CMS - Thank you sooo much!!!
Just working on my first site now but hoping it won't be too long
before I can contribute.
