Consider creating a "secret" variable type that automatically handles sensitive data and masks input during prompts, which also should be set via .env file and not directly in the compose files or other templates.
Implement multi-file support for templates, allowing jinja2 in other files as well
Mask secrets in rendering output (e.g. when displaying the final docker-compose file, mask secret values)
Add support for --out to specify a directory
Add support for more complex validation rules for environment variables, such as regex patterns or value ranges.
Add configuration support to allow users to override module and template spec with their own (e.g. defaults -> compose -> spec -> general ...)
Add an installation script when cloning the repo and setup necessary commands
Add an automatic update script to keep the tool up-to-date with the latest version from the repository.
Add compose deploy command to deploy a generated compose project to a local or remote docker environment
