I love it, would you consider after the fact "edits" ? like I want to use it for DM for some homebrew campaign, love the initial randomness, but sometimes I'd like to tweak (remove a room, add an entrance, ...)
People ask about it a lot, but there is no easy way to implement it. You can try to export a map as json and import it into one of editors supporting such json's (RPG Map Editor, Mipui).
