Sorry for the delay..
1) I like how things are looking.
2) I found these for conversion. Not sure if they will help:
Y = R * 0.299 + G * 0.587 + B * 0.114
U = R * -0.169 + G * -0.332 + B * 0.500 + 128;
V = R* 0.500 + G * -0.419 + B * -0.0813 + 128;
2) The colors aren't working very well yet. I understand that the highlight bar conversion is inaccurate, but other colors are off too. I guess this is a palette issue. After settling the layout stuff, I'd like to take another pass at all the colors. It would be nice if any ML colors could be specified in YUV (or RGB), so tuning isn't so mysterious (to me).
3) Can you move the two help lines up 2 pixels?
4) The forward icons are not left justified with the text for me, need to move left 6 pixels.
5) The forward icons should be full white like the text.
6) I think we should get rid of the "tab" treatment in the menu bar. With increasing number of icons, they are getting so close together than there's little room anymore. Also the black tab background can be hard to see depending on final contrast (yes the outline helped, but that's another issue). So I'd rather tune the three colors (background, active icon, inactive icon) so that the UI is clear and clean. Without removing code, can you make the tab color the same as the background for now, so we can try tuning colors with that out of the equation?
7) I know you like to relax line spacing when you can, but I feel that in the 11-row case, the crowding between the bottom of the list and the bottom bar is a worse issue. To my eye, the padding above and below the list (as when the scroll indicators are showing) provides needed relief for the eye, and makes the whole layout, including the list, look less dense, even when the lines are tighter by 1 pixel. Uniformity of placement is good and I feel that the line spacing should be the same everywhere. These small things mean a lot towards achieving elegance. Perhaps you can tighten the spacing by 1 pixel as I suggested, and then after I have a chance to tune everything to the best of my ability, if you think there is a problem, we can revisit?
8 ) Regarding Canon fonts etc, are you suggesting that we put all the menu icons in an rbf font? Makes sense. Can you think of a programmatic way to port them? Otherwise I could recreate them manually, but ugh. Tell me either way.
9) I see a "G" menu in your screenshot. What is that, and is it part of the build?
