ooo, I've heard this idea for quite some time now.
What I thought a while back would be that we could use objects, somewhat similar to picking chests and laying them on the level, only that images could be done the same way.

BUUUUUT!!!!
Now that we have setshape2. We can get those images in the level, then we can alter what type of sprite action we want while the player is over those tiles.

I also remember hearing Galen say somewhere that the NPCs are laid in the order in which you put them in the level. But I can understand that some people may want to edit those properties.
The three layers sound very good. One ground layer, one mid-level layer, and another layer for things higher in the air, perhaps above the player's sprite.
Stefan could possibley add this feature as a tile properties in another part of the Graal level editing window. Image directories could be imported into levels like they are imported into ganis. Then all what would be needed would be the images for second and third layers(first layer would be the tileset itself), and scripts for the second and third layer NPCs for effects(ei birds, fog, clouds, etc)

I hope I helped some instead of annoying anyone.
