Suggestion 1:
Add a Show compact search results list option that shows the search results in the same compact way as the global search. This make’s the search results less bloated and easy to read when I don’t need to see all the parent details.
AND/OR
Suggestion 2 (maybe a better and easier solution than suggestion 1?):
Add a lists: keyword to the global search that filters down the results to one or more specific lists.
