WEU Enhancer Settings

In the create map dialog and in the edit map dialog you will find this
tiles listbox that reprensents all the ground textures available in your
map.

After having activated the custom tileset checkbox you will be able to
add new tiles by clicking the add button and clicking one of the tiles
in the tile list. To remove a tile simply select it and click the delete
button. In the edit map dialog you are also able to replace tiles by
simply selection the tile, clicking the edit button and choosing the new
tile.

If you added new cliff tiles to your map, you will be informed that you
shouldn't use this tiles for creating cliffs after applying your changes.
What this means will be described below.
