Feature summary (what you would like to be able to do and where):
https://en.wikipedia.org/wiki/User:Novem_Linguae/Scripts/NotSoFast.js is a user script that, in Special:NewPagesFeed, highlights the creation date of articles newer than 15 minutes red, and newer than 1 hour yellow, to discourage reviewers from reviewing an article too soon.
Per WP:NPP#Care, "Outside these exceptions, an article should not be tagged for any kind of deletion for a minimum of 15 minutes after creation and it is often appropriate to wait an hour or more."
Per the doctrine that PageTriage should be a one stop shop for new page reviewing and not require the installation of any additional scripts, @MB_phab suggests that we incorporate this feature into PageTriage.
