Currently, FME Workbench allows users to define parameters in custom transformers or published workflows, but the ability to provide detailed guidance for each parameter is limited. I propose adding a new feature to User Parameters that enables authors to attach rich descriptions to each parameter. This would include:
- Formatted text (Markdown or HTML)
- Web links to documentation, tutorials, or external tools
- Images or diagrams to illustrate usage

When a user runs the workspace, they would see an information icon next to each parameter (show it only if it has content). Clicking this icon would open a dedicated window or pane displaying the enhanced description, helping users understand the context, expected input, and any dependencies or external resources required.

Benefits
- Improves usability and user experience, especially for complex parameters.
- Reduces support requests by providing self-service guidance.
- Enables better documentation and onboarding for new users.
