For example, if I select the values shown on this attached image (only modifying the part at the very top of the settings) and then generate a map, it will generate one, but if I remove the scaled view, it will appear an error and the program will close. I believe maybe with the custom images selected it may cause bugs, turning the map "heavy", because I remember using the program and sometimes when I clicked generate map, the progress bar didn't advance, so I would wait forever and the map wouldn't be generated, so I had to manually close the program. But the way it is, it's already is possible to do a lot of things. And, yeah I missed a text box to add to the map, good to know you plan to implement this.
About my map, I edited it on paint to write the text with the name of the map and its author (even though the program itself did like 99% of the job), then I converted the map to 113 colors using gimp. I don't know if 113 colors the transparency is worse or not, but I always converted to 113. I also painted the transparent area of the map to black on paint before the conversion with gimp. In the map editor, I raised the water level, changed the "level" to the "art" one even though this would be only useful with 64 colors which would remove the quality of the pictures and the background effects would appear hidden by the bottom part of the map. I also added Border because I think it is better looking this way, the screen only shows the map itself not it floating on a large area. And the map is a cave, there is no open areas to make it open. Ah when I saved the map after my changes in the map editor, I believe it changed the transparency too, because the map background was black and when I saved there it became transparent again (seeing the image externaly with a viewer program).
