- Yes. Right-click the region name and choose "Edit name" in the context menu.
- Maybe in the future I'll add the ability to mark hexes with "pins" like in MFCG, but not anytime soon. In any case labelling every hex this way would look ugly. Numbered hexes will be implemented soon.
- To make maps editable in this generator is not very hard, but it would require much time and this is not the sort of coding I like. You can hide towns, dungeons and roads via the Details submenu of the context menu.
- There is no way to add or edit assets because there are no assets here. Every icon is procedurally generated: for example if I wanted to add palm trees to the generator I would have to write a method for drawing them, not to draw them manually and save it as an image.
