I'll add that to the list of features. I'm hoping to get to some updates soon once I get out from being buried with work! In the meantime, you could hard-code that in by updating hungryfeed.php around line 254 this line:
$title = $item->get_title();
just below that you could add a line to truncate the title, as a simple example:
if (strlen($title) > 25) $title = substr($title,0,25) . "...";
