In the new ArcGIS online viewer, it is no longer possible in the Visualisation tab of a layer to quickly put check marks for each field to determine if they are visible and/or editable. This is now done by going to the Data tab, select a field, and then use the option to make a layer editable (or no longer editable). This is very labor intensive and time consuming, especially as we have several datasets with more than 120 fields, that are used for 9 hosted layers each. That's a LOT more mouse clicks then before to prepare them for our fieldworkers.
It would be really appreciated if Esri develops an easy way to change those attributes, so that they can be viewed and/or edited, similar to how it was done in the old viewer Visualization tab for each layer.
