WTH: Why can't we have a comments field for Helpers?

Since Helpers have moved from yaml to the UI and gained increased functionality I’m creating more and more of them. However, we have lost the ability to add comments to document where and how they are used.
An extra field to add a line or two of comments would server as a very useful aide-mémoire.

Thanks!

Is the smooth situation where Labels (tagging) is needed?
