In Workflow you can create a feature and add it directly to an ArcGIS Online map layer using the URL, however It would be helpful if that could be tweaked to save into a folder on a local device.

This would allow the user to run the workflow offline using Geocortex mobile then once back within mobile coverage, the feature layer could be updated in ArcGIS Online to reflect those changes. The file picker activity in the display form allows access to the photos on a mobile device so why cant features be stored for later retrieval?
