It would help me know where I am in my tree if I could see in the edit screen who the current person is in relation to the tree's root person.
This is something that Ancestry does and I find it a useful feature.
I know I can use Tools -> Relationship Calculator, but that takes time!
There is lots of space for this information to be shown at the top of the edit screen where the current person's name appears or, perhaps better, at the bottom where we have 'Last edited'.
