I wanna change the scale bar to be in the thousands of kilometers rather than hundreds of meters. The latter works well for small medieval cities, but not so much for modern/sci-fi cities.
Even if you set the size manually, you won't be able to get a city large than than 15-25 kilometers across.
I know this post is old af but I do think there's a genuine use case for this that doesn't involve making cities beyond the technical limitation of the generator. For example, there doesn't seem to be a way to change which units are used for the scale. So if I wanted to use Yards or Miles (not because I actually want to myself, but because certain super popular rulesets for TTRPGs are based on Imperial units) I could not find a way to do so. If it already exists, then it might just be an issue of potentially needing to change the numbers, since 100 metres and 100 yards, for example, are not the same size.
