One of the complex functions I will have to implement when moving clients form D7 to Backdrop is Maps. On D7 I use getlocations, leaflet and Open Street (not Google). I tried a dozen combinations of modules in D7, and I finally got one where everything worked together. I would love to see if this is possible in Backdrop.
I have several content types (plus taxonomies) - and I use views to display a single interactive map of distributors. Then I have a block with a contextual filter displaying a map on each distributor's profile page. (Please note that Distributors are not users, they are just a content type.)
