The app needs to display better the photo requests. Right now they are extremely random sometimes showing the name, sometimes the comments a person wrote, or whatever.
When you are in a big cemetery trying to fill requests you have to stand there and hunt through the requests to find the one you are ready to do. You have to change the app so that it consistently shows the name of the grave requested first. Then it would be quick and simple to fill requests when you are in a cemetery.
