After installing the widget on my side bar it works fine but looks VERY plain and unattractive.
Is there a way to make it look more up to date or configure the look. IE: box color, background color, size, style etc?
If you theme has not good CSS for form in the sidebar you should code the form manually, there is no other way. You can copy the form source from the list building/subscription form fields panel. WE’re taking into consideration to apply default forced design of the widget.
