Playback menus

There are four playback screens - ranging from one with no information at all... ...or ones with full shooting information, including a histogram, often useful for assessing exposure.
A third option allows you to zoom in on the focus point (or shuttle between faces if the camera has detected them). There's also the default screen which just tells of the image's number and time and date.
There are four levels of thumbnail view for navigating around your images. They range from 2x2... 3x3, 6x6 and this, 10x10. This most dense option makes the thumbnails unhelpfully small.
The 'jump' option allows you quickly scroll through your images using a series of criteria. The delete button, which can be used in any view, gives you the option of whether you erase the JPEG files, RAWs or both.
