When I use a digital camera I can point at an area and half-depress the shutter button to 'lock' the auto exposure; Can a similar toggle be used for Enscape? (Hot key?)
I find that when I'm navigating and the sky comes into view, the auto-exposure darkens to compensate (as you would expect) and the detail of what I'm focusing on goes too dark to see properly. I suppose if there was a slider to adjust the amount of influence the sky has in the image then a "lock" wouldn't be necessary. Perhaps a % of the sky visible on-screen before it is included in the calculations?
