It looks like our old forum thread was lost during the great forum move of '12, so here's a new thread!
For those that don't know,
is a flash based city planning and layout sharing tool I developed for this game.
The easiest way to use this tool is to install the LoU Tweak Chrome Extension or the LoU Tweak GreaseMonkey script firefox and click on the "Open in Flash City Planner 2" link. This will open up your city in the planner where you can easily manipulate your cities.
Once optimized, you can click the Import/Export button, copy the city layout blob, and paste it back into the LoU Tweak "Overlay Layout" box, which will then provide a nice overlay on what needs to change in your city to match your design.
If you have any problems using the tool, or have any questions, please post them here or email them to firstname.lastname@example.org
