I have ancestors that have many duplicate sources. For example, it seems like you can link to the Social security death index from different databases. This leaves me with a long list of sources that is visually overwhelming. I would love it if the sources could be filed and organized--either by the individual user or automatically filed into primary vital sources, census records, military records, or attached to someone else's primary vital source (as a parent on a birth certificate for example). This would help make looking through sources much easier.
