We would really like it if it would become possible to name the photos you take with the Collector App. At the moment they are named automatically; "photo 1", "photo 2" , etc. It is possible to rename them later in ArcGIS Online, but then you have to rename them per photo. When you made about 1,000 photos this is not doable. Therefore, it would be nice if you would be able to name your photo right after you took it with the Collector App.
