thanks for the great plugin!
unfortunately in my case it was going to be used by people with no knowledge of english, so i had to modify the plugin in order to be able to add a translation to it.
load_plugin_textdomain( 'wpupw', false, 'ultimate-posts-widget/languages/' );
to ultimate-posts-widget.php, created a "languages" folder and put wpupw-default.po, wpupw-default.mo, wpupw-it_IT.po and wpupw-it_IT.mo in it.
plus, i've added a class to the ouput list:
echo '<ul class="upw-list">';
to better handle the styles (and possibly target the list with some fancy jquery).
how can i submit the lot to you?
