I noticed the different icons--at first glance I'd guess it was to control screen brightness level?
Your comment on the .bwf format and the autosplit feature is a bit cryptic . . . anyway to confirm seamless splits will be a feature? Really that's the main thing I'm looking for; since I only use it as a bit bucket, the increased gain range, true 48V phantom, and faster transfer time (I use a card reader, anyway) don't matter to me much at all. Seamless splits, though, would likely make me pony up for this.
