The latest update to KitKat 4.4.2 on my HTC ONE added a new Theme section to my Personalize settings. Right now, it just lists out four pre-defined themes, which appear to just be a wallpaper and a set of colors which control the global theme of the phone and apps.
Currently, the most bearable for me is the all black one, but the button colors with it are green which is kind of annoying me. I'd love to be able to modify them to be blue, but I don't see any way to modify the themes or even add my own. There's no additional menu when viewing that screen, no popup for long-pressing a theme, nothing. You can only select one and click Apply.
Is there a simple way to add my own themes to this list, or is there even a way to add themes to this list?
