I just recently discovered your city/village/dungeon generators and am HUGELY impressed by them. I plan to post some minor tweaks, suggestions, issues, questions, etc; but first wanted to state that I am clearly a fan. I like the end-product, the visual style(s), and the algorithm and behind the scenes workings.
3 Issues I'm currently experiencing (across all 3 generators) are:
1) Exporting as PNG or SVG don't appear to be working correctly; instead giving me an odd multi-colored image with no structure.
2) Hotkeys that involve the Shift+ (ie: increase water level) dont recognize the “shift” and instead just function as the regular hotkey (toggling water on/of)
3) Having a way to see (or ideally save/export/import) the seed/keys/etc for an particular generation would be VERY useful to many people.
