Animate file create/delete

For now, if you delete or create a new folder, there is no nice animation, it just appears or vanishes. It would be very eye pleasing to have an animation, where the folder zooms in and out from the center, like it has a size of 0x0 and then transforms into correct width x height, like the other folders, or the opposite, if you delete it, shrink the folder to 0 x 0.
