I am testing out the show title feature, thanks for adding this. If I uncheck the show title box, it seems the plug-in is still generating an empty <h2 class="widgettitle"></h2> tag.
In my case this is a problem because I have a style for h2 that shows the border-bottom. Even though there is no text, in the tag, the border still displays. I can probably work around this using CSS, by removing the border for only those h2 that have class widgettitle. But I would prefer to not have the title tag at all.
Is it possible to update the plug-in so that it does not print the <h2 class="widgettitle"></h2> tag at all?
