Separation (not just unmerging)
Situation: 2 people look the same, and even have sources that belong to each other. A well-meaning researcher (sometimes me) decided to merge the two. After adding more sources, it became clear that this was 2 people.
Upon inspection, it doesn't make sense to unmerge them since they had some of each other's sources, I instead need to separate the individuals based on the virtue of their sources.
It would be nice to have a "Staging Area" where I could drag and drop each of a person's sources into groups (proposed new individuals).
If the sources all look right, it would be nice to detach them in bulk, and either attach them to an existing individual or create and attach them to a new individual. On organization tool even without the bulk operations would be nice.
I found a relative that was possibly 3 people combined with many sources and a sandbox area, or staging area where I could organize a proposed set of changes for sources would help. Right now I have to use a text editor and it's time consuming to get right. If there's an existing tool for this already, please let me know.
