I think you are getting at some needed functionality for me, too, but I can’t actually understand what you are talking about, sorry. The only place I’m not aware you can reference entities is in the plain text boxes that are available:
Refer to Comments, and Public ID’s for Comments. This is actually available already in ClickUp and Asana. When somebody says something in a comment you want to quote elsewhere, it would be great to grab that comment and refer to it.
And I agree the linked highlight I have not found useful, in fact we never use it, but probably link to 100’s of entities and views around Fibery daily because that is such a great functionality!
