Group layers in a WebMap are a great way to manage the limited screen real estate on a mobile device, but the current implementation of group layers in FieldMaps leaves a lot to be desired since there is only one button to control visibility and the collapse/expand state. Almost all my maps used by FieldMaps have a group layer that contains reference layers that are not editable and I should be able to collapse this group layer without affecting the visibility of the layers inside the group layer
