Hello, The easy question first. To change the size of the "universe" go into the menu Other --> Axes and Panels and edit the "Region" (sixth) column in the second table ("Axis types"). On the GFT front, I'll have to ask some people more about this before I can comment sensibly (maybe Tim can say more but he's at the EENC this week).
