two suggestions for Zone Adjustments

[davidh]

Is there any advantage to having both methods of switching before and after in Zone Adjustments?
B seems to cancel Display preview and Display I/O Side by Side buttons functions. If B is used, all display buttons show identical output: Before.
The Display Input/Preview buttons seem to be quite faster then B/A buttons and therefore preferable. I guess B/A buttons are redundant and could be removed.

My other suggestion is to make No Histogram Expansion the default value (PWP style) instead of Medium. No Expansion shows the histogram hills and valeys best of all three options.
The other two flatten the steepness too much. I guess their purpose is just to find the black and white points in cases either might be hidden below the bottom.
I like the new solution used in Brightness and Color curves, Stack Images, Autorange... Just two arrows: up/down.
