I don’t need the histogram or profile windows but I think it might be useful to have a preview of the current photo I’m editing with the Overexposed option (O on the keyboard, which also shows underexposed) applied so I don’t have to keep toggling it as I use the various modules. Perhaps there’s some way of doing this already if you could treat that as a style? If so, I’ve failed to figure it out. I guess there’s no reason the RAW overexposed (Shift-O) functionality couldn’t also be exposed/surfaced in this way.
