Occasionally, I see what should appear in the "empty" tiles in the tileset. (I know I can select and place them to see some of the future sprites and such, but in the editor they appear empty while in the player they actually show up as they should.) Is this intentional? Just an issue of version management?
For that matter, it would be nice to see in the interface what version I'm looking at, including ensuring I'm seeing the correct images somehow. : D
