In the last releases (1.6d and 1.6e) we introduced two new styles, "Logo only" for 1x1 widget and "Big logo + signal" for 2x1 widget, both have been inserted in place of two styles ("Ghost black" and "Minimalist black)" that after the possibility of managing the text color were duplicated.
If you liked those styles you can use "Ghost" or "Minimalist white" and set the text colors in the preferences.
Thanks
