How do you make the tech tree screen longer? I want to add some more techs to the end of the tree, but I don't know how to extend the screen to hold them.

Each tech has an "iGridX" and "iGridY" value. X = column, Y = row.

The higher the X value the further to the right it is. The screen redraws.

So basically just make sure your X values are higher than the existing X values. :)

Oh right! I didn't know it was that simple. Thanks, Dale.
