    It's great now that ArcGIS online supports relationship classes. It makes it easy to insert multiple inspections on an asset.  However, it's difficult for an inspector to visually see which assets they have already visited.
    I would like to see the ability to symbolise the main feature by a statistic of its related records eg. Count of attribute from related records.  Currently you can add that statistic to the origin feature's popup. We just need to add ability to symbolise by that value.
