The URLs to items in AGOL are difficult or impossible to remember. In an items properties add a string that can be used in an URL to open the item. e.g. instead of https://abc.maps.arcgis.com/home/item.html?id=12345abcabcabcabdbdac be able to make the URL https://abc.maps.arcgis.com/home/alias.html?alias=ParcelViewer that would redirect to the item's page. The alias text can be just defined in a text box n the Overview or Settings section on the item's page.
