I love all of your generators, and really like the editing feature of the city generator. Would it be possible to add something similar to that to the mansion, so that you could alter the shape? I don't do programming myself, so I don't know if that's a really difficult thing to do.
In this generator a mansion is fully defined by its ground plan (+ style settings such as colours, roof shape), everything is derived from it - how many floors there will be, into what rooms each floor will be split etc. It's relatively easy to implement a ground plan editor, it would look like a grid with square cells to check/uncheck. But it seems to me that's not what people would expect from a "mansion editor". Anyway, I will consider it.
