And what's even more funny is that the only thing that's preventing this is that Nokia hasn't hildonized it's own built-in programs to follow theme coloring all the way. For example they have made calendar to follow background color set by theme but then they have hard coded some font colors NOT to follow what theme is telling to use :-/ I don't know why they have chosen that path in severall apps included in N900. Since they already made the programs to take some colors from theme, why on earth they didn't make same trick for all other elements...
