Acorn Prettify is a development tool designed for developers working with modern CMS-based projects, particularly those using the Roots stack. It replaces the older Soil plugin, focusing on maintaining and improving core features for cleaner, more efficient website output.

Key features include:

• Cleaner markup: Removes unnecessary classes and IDs from the CMS's default HTML output, resulting in leaner front-end code.
• Nice search: Replaces the default site search with a more user-friendly version that uses a proper query string.
• Relative URLs: Converts absolute URLs within the site to relative ones, which can be disabled or configured as needed.
• Configuration file: All features are managed through a published config file, allowing for granular control over the tool's behavior.
• Composer dependency: It is installed and managed as a Composer package, aligning with modern PHP development workflows.
