Please upvote my idea if you think it is worthy. Essentially, the idea is to reenable true "Global Search" from the Lightning set up pages. Right now we have to jump out of set up, into a standard app, just to search amongst records, objects, reports, etc.
It would be great to have quick find still within set up, but not at the expense of 'Global Search' from set up.
