Hi Mike, cool site, I dig the logo.
I am planning to add an option to open links in a new window, but for the time being, this would be a pretty simple customization to make.
In the meteor-slideshow.php file, on line 33, change this:
<a href="<?php echo get_post_meta($post->ID, "slide_url_value", $single = true); ?>" title="<?php the_title(); ?>"><?php the_post_thumbnail('featured-slide'); ?></a>
Into this:
<a href="<?php echo get_post_meta($post->ID, "slide_url_value", $single = true); ?>" title="<?php the_title(); ?>" target="_blank"><?php the_post_thumbnail('featured-slide'); ?></a>
That adds target="_blank" to the anchors so they open in a new window or tab.
With this customization it is all or nothing, I'm hoping to setup the plugin so that you can choose which slides open in a new window/tab and which don't.
