• Fixed an issue where selecting terrain or furniture would sometimes populate the search box with junk. The junk has been evicted.
• Added an edit box for choosing an overmap terrain ID. Now the JSON files exported are actually loadable by CDDA, yay!
• After you draw a zone, it will become the selected zone, making it easier to edit the group and properties of that zone. No more wondering why changing the group wasn't working!
• You can now open files, as well as saving them. What incredible technology.

Also, there's a Linux build now! I haven't tested it, so please let me know if you have any trouble!

It is pitch black. You are likely to be eaten by an exception.
