Doing mouse-over on a name in the "In this photo" area shows the location in the picture of said person. Implementing the functionality when reviewing a document would be useful. Suggestion is to activate the green frame showing the area referenced by the "Identify"-function when doing a mouse-over on the name under "Profiles" (right hand side of image on the http://www.geni.com/documents/view?doc_id=xxxxxxxxxxx page).
Useful e.g. when asking for assistance from others in interpreting old hand-writing to quickly tell where you want others to look. Now you need to move the mouse over the whole page and there is nothing indicating that the "Identify" function has been used either.
