Default focus on Home screen menu item

I am currently using Aeon Nox 4.0.3 and can't find a way to set which home screen menu item I would like to be in focus when I first start up XBMC. I've read a couple of other threads where there have been mentions of editing an xml file but I've been unable to locate the files or lines mentioned.

Can anyone please tell me how you can change this for Aeon Nox?
