Tile texture selector. There is a bug in the official map editor that renders most tiles in white until you click on them. This program solves this problem by using its own tile viewer that syncs with the map editor when you click on a tile.
Sector added map list editor/code management window. Ben Millard fixed some bugs, made various changes to the GUI, made the window always on top, and changed the tile viewer to adjust the number of columns and rows to show when resized.
In addition to the program itself, the archive also contains its source code.
