I'd like the ability to customize the copyright text that appear in the bottom right of web maps/apps in AGO. I create maps with many layers, some of which I do not own and come from other departments within my organization (and I can't change the actual text of those ones). I'd like my name to appear first in the credits and/or be able to cut down the text as it can be overwhelming with many layers. The order in which the credits appear is dependent on the order in which they were added to the map. So, typically the basemap credits are first.
I suggest the ability to toggle the copyright text on/off for each layer and to easily re-order them.
