As most of you know, when it comes to Symbols and Fill Styles, we have Vintyri Cartographic Collection, Bogie's Mapping Objects and CSUAC, as well as other resources.

However, I was recently thinking: are there 3rd party tools or add-ons that add beyond art?

For instance, these were available for CC2:
Mappa Harnica Toolkit
Realms Overseer 3D and City Overseer 3D
CC2 IconBar Designer

Also, for FT there's:
Wilbur
Terraformer

Are there any other tools you know of (either commercial or free) that add functionality to CC2/CC3/CC3+ ?
