Make first category on category tabs automatically show.

Hello !

I would like to know if it is possible with this code to be able to automatically make the first category already be showing when I visit my forum ? The coding that I am using can be found here (http://www.webartzforum.com/t2933-showing-categories-as-tabs) and my forum type is currently phpBB3. Thank you in advance for any assistance !

My forum: http://www.timefortesting.forumotion.com (this is where I just test my coding before I put it on my main site.)

Hi,

Something like this? http://awesomescreenshot.com/0acvwfvf3

Can you please provide me a test account that has access to the Administration Panel, I want to play around with the code to see if it works properly before giving you anything.
