I just got the update... my SDext2 shows up on my root files list, very cool. Can see all my "link2SD" .apks now. Not sure if that's a good thing or bad thing, but nice to see what in there!
Not sure if the wallpaper background is necessary, black or selection by color is probably adequate. Even at 30% I had too many light spots making text less readable, I turned off wallpaper (should probably be off by default). Probably not so bad on a tablet.
I see beta is ending Oct. 10th... that's my birthday, do I get free real version?
