I expected to see a plus button in the lower right corner.
This is on OS X 10.11.6 using Tiled version 1.1.4. This is a small window for this post’s sake—resizing it does not make a difference. This is also after creating a tileset.
Are my assumptions wrong somewhere? Or is this a legitimate bug?
What changed since Tiled 1.0 is that while you’re editing a map, you can’t edit a tileset. This is because there is a separate undo stack for each file, and tilesets are now stored outside of the map by default (though even embedded tilesets get their own undo stack). So to add a Wang set you will first need to click the small “Edit Tileset” button in the Tilesets view, and then activate the Wang Sets mode.
Also, thanks for making this awesome tool! I was great help some years ago while prototyping a game (that never came to be). This time I’m just playing around with it for fun.
