Hi, Does anyone else feel that the screen brightness control in the bottom quick access panel is not very "real world" useable? EG., When I access the panel to tweak the brightness of the screen I'm reading (perhaps it's an all-white bg, etc.) the whole screen goes much darker (by design) - rendering my brightness tweak a "wild guess". This is akin to setting volume levels with no tactile feedback (i.e. no sound while adjusting). Seems like a real basic UI mistake, or am I missing something?? Thanks.
