Treemenu.php Help - Adding Item Counts

[GeekyGirl]

I am using a web program called Inspirations which is an interactive quote library.  You can see it in action at http://www.scrapuniversity.com/Library/Inspirations/index.php?cmd=1

 

The program uses treemenu and treemenuXL for the dynamic menus.  There is one menu within the admin area that includes an item count for each category (see screenshot).  I want to duplicate this concept with the main menu seen at the link above but don't know where to look to find the code.

 

Can anybody give me a little direction as to what and where to look?  Is it part of the treemenu or javascript file?  Or should it be in one of the php files?

 

I actually don't care about finding the existing code if someone can help me add the code to the main menu instead.

 

Note:  I am a newbie when it comes to php so a step-by-step is helpful.
