You're welcome; I'm happy to have a chance to give back to this community.
What do you mean by "version 1"? What are you looking for specifically...I went as high as 0.2 and it's working fine for me so I left it as-is.
I figured people could modify it to their liking and post updates. If anyone comes across anything mind-blowing with respect to the backlight (like how to make the sensor work consistently and not cause the scale to get shifted once in awhile) then I'd be happy to keep updating it.
