This feature request came from Kristen for her field mapping ! Kristen can add more info on this

I would like to be able to display a map showing the changes made by a given set of usernames, during a given period of time. Right now, the API only supports giving me the aggregated numbers (example: number of buildings added). Instead, I would like an API that will give me the buildings/roads/POIs (as seen on the latest snapshot) that were modified, so I can highlight them on a map. I would also like if this API provided me the changeset associated with the user' change, so that can be displayed in a popup. This is useful for monitoring, evaluating and validating changes made during workshops, small field campaigns and focus groups.

This sort of map/functionality was requested during my observations of OSM organizations in Tanzania, as well as being valuable for my personal projects.

Eventually, I hope to display this data in a map, and allow a user to download the full set in a csv.

I'd be interested to learn a bit more how large your bounding box would be, how many different users names would be in scope, and also what the relevant time period would be like.
