jupyterlab_templates

Requires manual editing of jupyter_notebook_config.py for setup, which can be non-trivial for users unfamiliar with Jupyter's configuration system and adds deployment overhead.

Templates must be placed in subdirectories of parent directories, not directly in parent dirs, which enforces a specific organizational structure that might not align with all user preferences.

Only functions within JupyterLab, making it incompatible with other notebook interfaces like Jupyter Notebook classic or cloud platforms (e.g., Google Colab) that lack Lab support.

Lacks dynamic features such as template variables or integration with external APIs, relying solely on predefined static files, which limits automation and real-time customization.
