Make's sense :-)

A Horde_BlockLayout class would make sense to me, having funtions to:
render() the blocks to screen in normal and edit modes
serialize() and unserialize() to give a storable form of the block layout for
loading and saving in prefs or what ever.
addAt(block, x, y), removeAt(x, y) to add & remove blocks
moveLeft(x, y), right, up, down to move blocks around
expandLeft(x, y), right, up, down to resize blocks

Well that was my long term plan but i haven't had time to code any of it.
