I used this add-on because I had to make page content well arranged without overloading the main navigation.

At first I did not know how to handle this add-on. You have to create a stack with boxes, in my case content boxes, for every tab you need. Then you have to give the user template a name, and that will be the text on the tab.

Once understood, this add-on is so easy to use and so helpful. Of course you can design the appearance by CSS.

This add-on works great! It does exactly what it says it does, and it's very simple to use once you read the documentation. Aside from that, the support was fantastic! I was having issues, and the developer of this add-on was able to help immensely. Thanks so much!
Highly recommend this add-on!
