heres some probably not too useful feedback from heavy usage over the last few weeks:
1) night mode is perfect, and zooming videos is a huge boon

2) another oddball thing that would be really useful for me:
i could really use a toggle for recursive DCIM descending.
so i organize my photos right in the DCIM by event. most of the time, i just want to see what photos are loose in the root of DCIM, but occasionally i want to see the subdirectories contents.

3) i move the focus instead of capturing the pic ALL THE TIME, sometimes while looking right at it. fat fingers i guess.

id use the vol+ button, but its too awkward for one hand without covering the lens.

here are possible some solutions to this problem:
-make the capture button larger {like, twice as big, srsly}
-make it so you need to drag the focus target from wherever it is, instead of just touch a spot on the screen

4) most of the time, im really happy that the picture doesnt rotate with accel.
but OCCASIONALLY, i really want to see the pic rotated.
a rotate button would be perfect.
