Kind of how windows's old document-first paradigm worked. Of course we didn't have a name for it at the time since it was just how computers worked. You could open Word and select open, but 95% of the time you double clicked on a word file. You can't do this on phones for some reason.

The term "activities" icks me out though, it's totally not obvious what that means. Maybe it is obvious in context but it feels a bit like having every explorer window start with a heading "files and folders" or your desktop says "desktop". If it's really good UI you shouldn't need a label for the whole collection like that.
