No Documentation for Installing Code Editor Highlighting Themes in JupyterLab Desktop

As a user of JupyterLab Desktop, you may have encountered the issue of limited customization options for code editor highlighting themes. While the Settings menu provides options for Text Editor Theme, the choices are limited to jupyter and codemirror. However, there is no clear documentation on how to install new code editor themes, leaving users with unanswered questions. In this article, we will delve into the current state of code editor theme customization in JupyterLab Desktop and explore possible solutions.

Upon examining the Settings menu, it becomes apparent that the Text Editor Theme setting is limited to two options: jupyter and codemirror. While the Settings Editor provides a free text field for Theme under the Notebook > Custom editor styles section, there is no clear guidance on how to install new themes. This lack of documentation raises questions about the expected behavior of JupyterLab Desktop users and the possible methods for customizing code editor themes.

A review of JupyterLab's documentation reveals that there is no mention of installing new code editor themes. The CodeMirror documentation, which is used by JupyterLab for code cells, focuses on integrating themes into specific applications, rather than providing guidance for end-users. This lack of documentation makes it challenging for users to find the necessary information to customize their code editor themes.

Given the current state of code editor theme customization in JupyterLab Desktop, several possible solutions can be explored:

Installing a plugin: One possible solution is to install a plugin that provides additional code editor themes. However, this would require users to have knowledge of plugin installation and management.
Dropping CodeMirror theme files in a specific directory: Another possible solution is to drop CodeMirror theme files in a specific directory. However, this would require users to have knowledge of the directory structure and the specific file formats required.
Customizing the theme using the Settings Editor: Users can also try customizing the theme using the Settings Editor. However, this would require users to have knowledge of the theme's CSS and JavaScript files.

In conclusion, the current state of code editor theme customization in JupyterLab Desktop is limited, and there is a need for clear documentation on how to install new themes. While possible solutions exist, they require users to have knowledge of plugin installation, directory structure, and theme customization. To address this issue, additional documentation is needed to provide users with the necessary information to customize their code editor themes.

To improve the code editor theme customization experience in JupyterLab Desktop, the following steps can be taken:

Create a documentation page: A documentation page should be created to provide users with clear guidance on how to install new code editor themes.
Provide plugin installation instructions: Instructions should be provided on how to install plugins that provide additional code editor themes.
Document directory structure and file formats: The directory structure and file formats required for customizing code editor themes should be documented.
Develop a theme customization tool: A theme customization tool should be developed to make it easier for users to customize their code editor themes.

Based on the current state of code editor theme customization in JupyterLab Desktop, the following recommendations can be made:

Users should be provided with clear documentation on how to install new code editor themes.
Plugin installation instructions should be provided to make it easier for users to install plugins that provide additional code editor themes.
