It would be nice to be able to zoom the tech view in
Ideally this it would be a smooth transition between
zoom levels, like on the galaxy map, done with the
If this is problematic (due to scaling issues of text
and tree boxes or somesuch), just having two levels,
"in close" (as it is now) and "far out" / "big picture"
with less information about each tech displayed on the
tree itself would be almost as good.
