Suggestions, eh? Well, I didn't actually download your program, but just from looking at the screenshot I can see something it could use... You know how each level of the same tech has its own box? Well, that's going to make the whole tech tree take up a LOT of space! (Imagine the Propulsion tree... shudder!) What I'm suggesting is condensing all the nodes that don't have something branching from them. So instead of this:

Prop I -> Prop II -> Prop III -> Prop IV -> Prop V

By the way, what happens when a tech has 2 or more prerequisites? Do you actually have wild lines going all over the place, or does it just branch from the first one?
