Stack edited photos

After a while of using PhotoAI, the Camera grid gets huge. When editing a photo that was generated a while ago (i.e. is located further down the grid) the new version of that photo appears at the top of the grid. If you edit that photo a couple of times over time while having generated other photos in the meantime, it becomes a huge chaotic mess.

It would be much better if edited photos would be stacked or grouped together with the originally generated photos, along with all the other editions of that photo.
