XF 1.4 How to put forum categories in a tab structure?

I manage a big forum that has a lot of forums.
This translates in a long forum home with unconfortable need to scroll the entire page.
I would to move some big sections in tabs, so users can click on it and see only forums that are on their interest, hiding all others.

I drawn a sketch to let you know what I mean: forum tab.JPG

I hope you can help me.

Many thanks in advance.
