I would definitely like to see these 3 features in nos 3.0!
My wishes/suggestions:
1. If the wallpaper is too bright, allow the clock to be dark, same goes for some desktop widgets. They can be hard to read.
2. In addition, you could allow the clock fonts to use the monet color theme so that they match the wallpaper well.
3. Possibility to align the clock on the lock screen left/center/right
And as for the real black AMOLED theme - I would really like to see that.
