Great work! I purchased a license a few days ago and I can't stop generating maps. I'm loving it! So far I am exporting them to a simple JPG to upload to roll20, and my players have loved it.
Although there are a few bugs to fix, the application is wonderful. In my case, for example, the position of some elements located on the map (in the world selection) somehow get lost. It doesn't happen everytime, and I can't find a pattern, but sometimes, when I delete a map once in a location, all of them get deleted (even if you reenter the room, they appear again).
But as I say, this is not a criticism, but an attempt to help an excellent program.
Congratulations, and thank you very much!
