Thanks for the great work, Zeno42!
I have some minor suggestions for an improvement:
1.) A new tech added should have level 1, not 0. There is no tech level 0.
2.)The Ai state should be all "except the not connected" by default.
3.) Min % should be 50% by default.
4.) Your pull-down menus could be much bigger so I can see more tech areas at once. He, I have a big monitor!
Again, thanks for this great little program!
