The Quick Theme Editor is an add-on that simplifies the creation of custom interface themes in Blender. It condenses Blender's default granular theme preferences into a centralized set of color and style controls, allowing users to establish a consistent user interface layout quickly. The tool adds a new panel directly inside the User Preferences menu above the standard theme settings.
The add-on includes a feature to pull colors from an active theme to use as a baseline. It is primarily designed to facilitate the rapid creation of new global theme bases, applying broad color choices that can later be manually fine-tuned using Blender's individual theme parameters.
