I will admit a prejudice for being able to adjust the brightness level with as much of a page from the book in view as possible. It really does make sense as the amount of white space on the page is directly related to overall brightness/contrast. Because of that I'd prefer not seeing the menu bars at top and bottom during adjustment, and only seeing as narrow a brightness adjustment bar displayed over the text as is needed for comfortable access, preferably at display bottom.
I'll take it one step farther and ask why they can't simply use a long press of the Light button to bring up the dialog for brightness control, and a night mode option, since such an elegant and simple method has been found to work? Granted the night mode is not perfect due to the way contrast is slanted to improve normal text display with e_ink displays, but that certainly doesn't prevent the brightness dialog from being called up that way.
David for,
Apparently great minds not only think alike, they do it at virtually the same time...
