The Preferences Panel can be accessed very easily.
- Make sure Visual Developer is active ( it’s toggled )
- Click Preferences on the top-left corner in the Visual Developer Panel
If you want to limit the CSS options available in the Element Panel you just need to click them here, in this section, and they will be disabled.
This is an useful feature if you want to limit your customers in what they can edit, or simply if you want to personalize your experience with Visual Developer
