This plugin could be rated with 5 or 1 stars. I gave it a 1 as on any site I place it on that has drop down menus, they no longer work. The regular menus work fine but when you hover over a drop down menu, nothing happens. The drop downs don't drop.
So, if you have a site that needs drop downs, then this is NOT the plugin for you.
If you have a site that you will only use a single level of menu items with no drop downs, then this can work for you well.
As a full time website developer, I have tried this with four different themes and get the same issue with all of them.
