Hi Dopi
Changing the title property of your icon in your header.php will simply edit the text in your browser when the icons is hovered.
To change how your icon appears in your templates parameters you must edit the following in your templates templateDetails.xml (../templates/j51_oxygen/templateDetails.xml)..
<field name="nav_blogger_sw" type="checkbox" label="Blogger" description="Blogger" value="1" checked="checked" />
<field name="nav_blogger" type="text" size="40" default="" label="Blogger Url" description="Blogger URL" />
Ensure to only edit the 'description' and 'label' of each line.
