I would like the ability to make hosted feature/tile layers hidden from others the Web Map is shared with (but visible to owner). Due to the nature of map making, there are files that need to be shared (for functionality), but never opened by others. These files crowd the content of what is being shared. My current workflow is adding a ‘DO NOT USE’ warning thumbnail to the hosted feature/tile layers that I do not want others to confuse with the maps. While this works, it doesn’t seem ideal, and like there should be a cleaner way to accomplish this.
I've logged ENH-000172488. I hope you'll consider this.
