How to automatically move programmatically created windows to the first empty space

[lukas-kyeso]

Sometimes apps create new windows. Is there a way to hook into this and move the newly created window to the first empty space (starting from space 0). This is so I don't end up with Space 1 (Browser), Space 2 (Empty) Space 3 (Empty), Space 4 (Empty), Space 5 (Empty), Space 6 (Empty), Space 7(programmatically spawned window).
Alternatively a way to shift all windows such that there are no empty spaces between them after a window has been programmatically created.
