Theme packs affect XiaDown surfaces consistently, including the app documentation view. When documentation is opened inside XiaDown, the app passes current language, light/dark mode, and theme into the documentation page so it visually matches the product.

Use light mode for bright environments, dark mode for low-light environments, or auto mode to follow the system. Accent color affects selected states, important buttons, links, and focus highlights.

If text feels too dense or too large, adjust font size here. A font change applies to the app interface and helps make long task lists, tables, and documentation easier to read.

Pets are also part of appearance. They appear in the lower-left avatar, empty states, and running states. Open Pet Gallery to switch built-in pets or import online and local pet packages.
