Hi, I understand we can select from one of six Themes, and apparently that is where line properties are set (color, thickness, etc.) How do I customize a Theme?
Currently the Interface Builder does not allow any customization of Themes.
We will take into consideration of your request for future builds.
You can also reach us at firstname.lastname@example.org
As an addendum to what Geromel said, you can customize most of the themes with some knowledge of CSS. Let us know if you’re interested and i’ll send you instructions.
