 (I took a break. I'm active again, but Stellarium advanced quite a bit in the mean time, and some things broke when I merged these changes into my branch. I've readded ES 2 support and have to readd input/actions and look at a potential crash, but I'm just about back to the list again)

 The Action Bar logo (see [[Android_port/Specification]]; the icon on the far-left of the bar) should be larger than the other icons. It can be the same size as the launcher icon. In fact, it can be the same image as the launcher icon, or it can be a variant with larger margins, whatever works best.
-There's more details in the guidelines, but Google says they should be flat (not shaded, outlined, or shadowed), pictographic, and #ffffff at 80% opacity (*** I think it's a good idea if we just do the opacity programatically. Make the image 100%, have Stellarium do 80% or 30% depending on if it's enabled or disabled. Halves the number of images we need to bother with...). If we diverge from that, we should keep things consistent.

If we diverge from that, we should keep things consistent.
 If we're doing activated/deactivated icons like Stellarium does, the deactivated ones should probably still be fairly bright (near or at #ffffff). Mobile devices vary in screen quality, and are frequently used with low brightness settings and in adverse lighting conditions.
