First, CONGRATS, your plugin is really the best! Better than WP-o-Matic and FeedWordPress. I've tried them all... :)
I have a single "problem"/question/request: is there any way to grab the first image from a feed, and set it as the "featured image"? The plugin imports the image, which is great, but isn't there any way to set the imported image as the post's featured image? This will REALLY be helpful, as 99% of the themes nowadays use the featured image option.
