Tried to change list item font color whether using the color or font tools (rgba(x,x,x,x))
Couldn't do it.
Note that there are other controls whose style properties cannot be accessed from theme builder.
I suggest introducing keys to combine with mouse events, for example:
- default is changing background color (no key pressed while dragging a color over a UI object)
- when B (or Ctrl or whatever) is pressed, dragging a color over a UI object changes the border color
- when F (or Shift or whatever) is pressed, dragging a color over a UI object changes the font color
