The ArcGIS online update to the Gallery section was not good. It is very confusing for my non-gis users to see all the feature layers used to make the maps. Esri should turn on filter window by default and sort items by Apps, Maps, Feature Layers, etc. I would put key maps and apps in the home page but I have users who only have access to specific projects. Is there a way to control what different users see on the home page based on group access?
