Love this tool, it saves me so much time for a game I run it's unreal. I would say that for my use case (generating a large city map that needs to be consistent for my players) it can be very difficult to get smaller maps of individual sections of the larger city. A fully zoomed out .png is great for an overview, but the fine details which come through fine in the generator are lost even at the highest resolution download available, and I generally have to resort to recreating the layout by hand which is rather tedious, especially since the generator renders down to that level of detail already.
An option to divide a map into a grid and download each section as an individual high resolution .png file to better capture the details would be amazing. Right now you can sort of do it manually when the generator feels like cooperating, panning while zoomed and downloading sections of a map, but it can get sloppy, and a way to do that automatically would be wonderful.
I have no idea how feasible that would be to implement, but if it is possible it would be an incredible tool to have.
