Hi, guys!
We want to tell you about two new features:)
The first, you may import any image as the sketch of your map, to paint over it.
The second, you may generate map in d20 Random Dungeon Generator (https://donjon.bin.sh/d20/dungeon/)
and import it in the app, and it will create rooms, corridors and walls sorted in groups.
Let's look how it works now (this's not a final version, we always added doors, and have plans to add other improvements)
