Render URLs in text annotations as clickable links

Is your feature request related to a problem? Please describe.

Describe the solution you'd like

Render URLs found in text annotations (or somewhere else?) to make them clickable.

Describe alternatives you've considered

This may not be a core functionality but a reasonable extension module.
