I just installed this plug-in and it worked great. One of the challenging things for a newbie with StudioPress is getting the proper widgets together just so that it looks like the demo. Without the widgets installed - the templates look nothing like the demo. So the problem I had was to get a simple slideshow widget "Slideshow Gallery" and a the "Genesis Featured Posts" widget to work together. Unfortunately - one is a widget and one is shortcode driven which works well if the shortcode goes into a specific post or page. Or, you can be well versed in the Genesis framework and hard code the PHP script into the exact place to execute it (if you know where that is ...)
Luckily there is this plugin! No need to find the right file and hard code anymore. However to make it easy for users to add code necessary to make a widget work, I would suggest users go find the "Genesis Visual Hook Guide" plugin (on wordpress.org) to figure out where to insert the PHP code. Simple hooks will exactly mirror the names of the various hooks displayed on the page with the Visual Hook Guide and from there its easy to add the script to the right section of code.
