Expand Styling - Colors, spacing & hover when adding or editing an item:

• Colors: Background Color, Border Color, Border Radius (px), Text Color (colour pickers; leave empty to inherit the menu defaults).
• Spacing: Padding (px) and Margin (px) with separate Top / Right / Bottom / Left boxes.
• Hover: Hover Background Color, Hover Text Color, Hover Border Color.

Empty fields are stored as "not set" so the global menu colours apply. The Links list previews the colours on the title so you can check the result before viewing the site.
