Been thinking about this. It might be nice to have the option to somehow make this publication date visible if it is provided in the XML. I can think of four possible combinations that might be useful:
1. Status quo - don't make use of <pubDate>
2. Add the date to the box-over somewhere
3. Add the date to the actually feed title (so it shows up visible on the page)
4. Both 2 and 3.
Just a consideration for an enhancement. Since I"ve already mucked with the code in mainfile.php for layout purposes, I might see what I can muster up.
Edit: I know, I hadn't posted yet... lol.. But here is what I did and take a look at

I added this code after the setting of $item_desc:
$item_date = $item->get_date('F j, Y');
Then I concatenated into the title on both the text and the boxover. Me likes...
