This is just a little addon that extends the in-game design options for placeables.
Added slots for up to 8 different design configurations and up to 8 different color configurations.
This version also allows adding custom named configurations via the modDesc.xml file of any loaded mod.
Examples are in the sdk folder of this mod.
Finally, when creating new configurations, try to keep the same naming convention as other placeables.
Configurations are currently game limited to 127 total.
For example, if you want to make a roof color configuration and you know X other placeables already have one, use the same configuration name in your modDesc.xml.
This will keep slot usage to a minimum and will avoid over running the limit.
