We used this plugin on a client's website and it now gives them great flexibility to decide sidebar content without worrying about coding at all.
The setup didn't go as planned, even though we followed the instructions. However the developer helped us out and we can see how to get it right next time. So that was great!
Highly recommend the plugin if integrating into a site for a client who may not be familiar with HTML/CSS.
