I want the ability to define a default map in my profile. That way when I open map viewer, I get the layers use most frequently. If you are thinking well, just create a map and open that when you want to see that information, of course! But, I am often analyzing information based on other data and I find myself in other search spaces, like content, gallery, search.html results, even groups, and there is no mechanism to add a layer I find into a specific map. The option to open in map viewer creates a new map. The option to view details doesn't give me the visual, and they both navigate me away from my current search. If I had an option to "Add to default map" well then I would be able to continue to browse and when I am ready, view those layers in addition to all the other map layers I use frequently. I don't want open in default map immediately either, I want add to default map. You could have it be a map that you define as a default. You could also create a space in content called My default map. It's similar to favorites, but its taking it a step further. Maybe an organization could define a default map? You get to do so with a basemap, but not just a map? Even viewers should be able to have a default mapping experience. Consider implementing something like this please! Thank you!
