In much the same way that the crop tool in Photoshop has optional grid overlays (rule of thirds, golden spiral etc), Indesign could have the option to toggle these on/off for graphic frames.

This would be immensely useful for positioning images in graphic frames – for example when placing a headshot and wanting to align the subjects eye using the rule of thirds or golden ratio.

This would be far better than having to crop/resize images in Photoshop in advance, particularly because you can then adjust the size of the graphic frame in Indesign without having to redo your crop in Photoshop.
