[Tyhm]

Tyhm's wishlist:
1) Be able to write to bombs[index].y. I can fake it with remove and add, but as I found out, removebomb is laggier than putbomb - locally the bomb falls, globally a column of bombs appear.
2) Be able to write to items[index].x and items[index].y. Very difficult to make cool weapons that drag gelats towards you without duping. Easy to remove them and use a showimg, sure, but then there's no way to steal them in midair.
3) Writing to arrows and horses would be nice too, but I'm not holding my breath. ^_^
