If I recall correctly, the “Getting started” popup was drafted by me, then heavily revised by several members of the Paratext team. I think full attribution would be: Helen Barker, Danial Castle, Don Cheney, Jonathan Coombs, IanH , Todd Hoatson, Michael Lothers.
As for footnotes, it may be worth mentioning the version of Paratext which was used for the screenshot given that the UI can change significantly between versions. Enhanced Resources haven’t changed much since they were first released but there are improvements we’d like to make, especially in the formatting and layout of the research (lower) pane.
