There are a few things missing on 'new' overlays - namely WB shift values, left shots count and current exp. comp. While WB shifts are not easy to change by mistake and left shots can be estimated from storage space left, the last one is easily changed by Av+scrollwheel and there's no any indication on the screen. It would be nice to have it back.
It would be even more nice to make use of space next to the histogram or small waveform (if displayed) or make the layout fully customizable.
