Help me understand Day and Dusk

The new Day and Dusk feature is exactly the use case I was hoping for when I bought my LIFX+ bulbs last year. I wasn't able to reliably make it happen with schedules, so I was excited to see it was being implemented as a dedicated feature. But it doesn't seem to be nearly ready for primetime. Or am I just stupid?

First of all, can you not adjust the times/colors/brightness? eg Not everyone wakes up at 7, nor is sunrise at 7 every day/everywhere. It seems to me you should be able to adjust the color/intensity curve, but I can't figure out how. Dragging along it simply shows me the color temperature for that time of day.

Second off, it seems like any possible method of external control deactivates the feature entirely. I use Logitech pop switches, but it seems like they can't turn the lights on or off without picking a color/temperature. That could be on Logitech, but is there some other go-between I could use (harmony, IFTTT)? Additionally, when I do turn the lights on or off, they don't seem to ever return to the correct settings for the time of day, and the "change on" setting gets reset to "never repeat."

What I want is for my lights, when they are on, to match the time of day, and to be able to turn them on an off from a switch. I don't want this feature to require me to leave the lights on all day. Is this not possible? Am I crazy?
