We all know that planning your future city locations--while essential to the game--can be a real pain in the a**. Do you edit screenshots in Photoshop, print them out and use crayons, or wrestle with Civ4's line-drawing tool which only works when zoomed so far out as to make seeing tiles nearly impossible?
Just say no!
Enter the Strategy Layer: an in-game dot-mapping tool by Del69 and myself--based on Eunomiac's original idea. It works very much like the sign tool (ALT + S). You can add and remove colored city outlines with a simple click. As someone who used to use signs to mark future city locations, this is probably my new favorite BUG feature!
See the New Features thread for instructions on using the tool.
