Where should I post this for developers to consider it?
Anyway, my understanding is that a new theme will be provided for Ibex.
I assume the standard Ubuntu colors will happen again for the new theme, but I also think the developers should include at least three different color variations of the theme and its matching icon set. Maybe something like Standard, Green, and Blue. I think that would make the most people happy.
I also think they should remove those old Gnome themes that no one uses, like High Contrast and Crux.
