I've got a standard email query I share across workflows that sends an email on error, it just needs workflowContext to work, but can all accept a sendTo string to send the notification to more people.
The current description field in the workflow has a bug that if you put in too long of a description, it says it's too long (max len 0) and deletes what was there.

It would be great to have a place to add a bit of actual documentation to these shared functions/resources, maybe the description isn't the right place and it makes more sense in a dedicated area, but it would definitely be handy.
