Transition speed for grayscale mode
I really appreciate the new grayscale mode. It makes it much easier to concentrate when reading. One minor issue though is that the time it takes to transition between grayscale and color is too slow in my opinion (about 2 seconds under the default settings).
I found that by changing the option listed under the heading "How quickly should transitions happen?" to "Very Fast: Gaming" the transition speed is closer to about half a second, which is just about perfect for me, but it has the unwanted effect of also speeding up the daily color temperature transitions. It would be nice to have a separate setting to control the speed of the transition to grayscale while keeping the slow natural timing for daily color temperature changes, or simply speed up the default grayscale transition to something less a second.
