Hey @SoLoReAdEr

I noticed that the PR includes several additional properties that aren’t part of the official Notesnook theme schema. To ensure proper formatting and compatibility, could you please use the official Theme Builder to generate the files?

You can export both the .json theme file and the code-block.css directly from:
https://theme-builder.notesnook.com/

Using the Theme Builder will ensure the theme follows the correct structure and avoids unsupported properties.

Thanks!
