Currently, we are locked into a global theme (white, light, dark). I have chosen the Light theme for my charts, but there are instances when I would like to be able to view a chart with the Dark theme without changing all my charts to that theme. The recent blog videos for GoNoGo are a good example of where a dark theme really works well. My request is to make the theme setting in Optuma non-global so that a chart layout or page layout can set the theme to any one of the three possible ones without affecting other layouts.
