Random Category Brush

The best summary improvement to this would be per folder/subject have a random tool, simple (for us, a fair amount of Dev I assume). As a brush you can create massive amounts of random "Forest etc, which includes x% of trees % rocks, x% random. So -Create a New Map, Random Brush the different areas; forest, desert and lava areas for example, and each includes x amount of everything! Viola, then you spend a bit of time making certain edits and any map is done! Maps in Minutes! (I am a Business Analyst sorry ;))
