i have two suggestions:

1) system wide component title/listing style
now you have this in your list.php for styling titles

	<div id="poll_title">

		<?php echo JText::_('TITLE_POLL_LIST'); ?> 

		<?php 

		if($this->category && $this->categories[0]->id){

			echo ":" . $this->categories[0]->title;

		}

		?>

	</div>

but this is for the hole main website look a braking style, the mainly rest of my components get the default template title styling with componentheading. i would like to appreciate when you change your styling for a better uniform look.

class="componentheading"

2) wrong whitespace
in the file "root/components/com_communitypolls/templates/default/file.php" on "line 15"

echo ":" . $this->categories[0]->title;

now
TITLE :CAT
sould be
TITLE: CAT

{CJATTACHMENT ["id": 148]}
