In the same way that we can use the short-cut “M” to show/hide the mask - a shortcut (say, “B”) to activate/deactivate the B&W mask would be an excellent enhancement of the UI/UX … this would especially facilitate evaluation of the state of the current mask.
For example;
A very nice feature of the combination of Color plus B&W masks applies with these settings; - B&W Mask = ON, and Show Masks = OFF
Now, with the B&W Mask option = ON, but Show Masks = OFF, I can clearly see my image without the B&W mask being applied until I position my cursor over an LA’s U-Point (or its area-of-influence delimiters, or whatever, depending on the LA-type) … and then the B&W Mask kicks-in, until I move the cursor again.
This is very handy … and it demonstrates why a shortcut to toggle B&W Mask status (say, “B”) - similar to the “M” shortcut to toggle Show Masks status - would be an excellent productivity addition.
I see you are extensively testing and writing FR’s. Maybe I will benefit from it, if DXO ever fixes all the little bugs and inconveniences and I decide to buy version 7 after all. Doesn’t look like it at the moment, but never say never.
At this stage, I’m trying to keep things “simple and do-able” … on the basis that (hopefully) this will make it somewhat more likely that DxO will respond with appropriate updates.
