Question

Miss the option of viewing all people in find a grave plot listed when I search individual

Answer 1

You can see them on findagave if they have been connected there. You may find reference to them on an individual’s Wikitree profile if the profile manager felt it was appropriate to mention them in the biography. I cannot see any benefit in being able to automatically view them in Wikitree. I think that kind of functionality would just introduce another potential set of errors.

Answer 2

Not sure if this is what you're looking for but, there are more people links below the main entry.  Just scroll down a bit.  e.g.  My wife's grandfather (https://www.findagrave.com/memorial/30886352/jorensen) and below that are his wife (Margaret) and one daughter (mabel).  Plus several other general links to that cemetery, town, county, etc.
