Description Victor Engmark 2014-09-08 07:00:50 UTC
Over/Under exposure indication is one of many metrics to choose which photo to work with from a larger body of similar ones. It would therefore be great if it were available essentially everywhere, but especially in the preview mode.

Reproducible: Always
