It is simple Jillaine - we are also working with massively merged profiles. Separating the different GEDCOM imputs (with their sources) by date and name of uploader makes it much easier to collate the data. When working with tens, hundreds of profiles a day, going to the changes tab to try and untangle the input from various sources and try and ascertain their validity, is simply not feasible. I can also in one glance ascertain the "integrity" of an edited bio by looking at the distinguishing key elements of each GEDCOM (each GEDCOM has it;s unique DNA if you will ...). If something is missing, I know that there might been some data missing from the bio as well.
This request was made in January. We had the new boilerplate then and it meant revisiting the changes tab in order to re-construct the GEDCOM input in order to make sense of them. Since mid-June I think, the old situation was restored.
