do you mean color for text , or for the widgets themselves .. we do plan on creating a dark theme , as well as adding more coloring options to the widgets

I meant both the widgets and the text: I tried changing the color of the widget to grey and with the default text color it was very difficult to read, but I didn't see any way to change the color of the text.

Having the option to change the theme of the entire app or dashboard would be very desirable as a feature, at least to me.
