Here on the Forum, topics that get linked from other topics show a list of link-backs at the bottom of the initial post. For example, look at the bottom of the first post in this topic (to which I now just added another link!).
Is that what you have in mind for observations – a section on the detail page somewhere listing link-backs? If technically feasible, I could see that being very handy! Seems like there is often some white space to the right of the Data Quality Assessment section that could be put to such use…
