Please add the Option to change the font Color of Buttons.
Currently there are 2 different button styles selectable, the solid one has a hardcoded black font-color. In it's current state it is not usable if a dark button color gets used as the text is difficult to read in that case.
If the Button Text Color is settable through a hex value that would not be a problem.
At least an Option to toggle the Buttontextcolor from black to white and vice versa would be nice.
