Thanks for this very useful plugin!
I was wondering if there is an easy way to display only the post title, and not the post title linking to the single post.
If I remove all the hrefs from widget-query-posts.php it works fine, but then I would have to remember to change that everytime there is a new version of the plugin.
Currently I am using the option 'Title' instead of 'Enable entry title'. But the available space to write a title there is very small, and I need to enter it in more than one language, so it is kind of uncomfortable.
