I'd suggest removing the "FreeBSD src repository" clause from "What's cooking" search. The reason is, many src reviews are not marked as "src repository", for some reason. Also, why not include ports and doc stuff?
Where is this "what's cooking" search in https://reviews.freebsd.org ?
Left hand side, click "Differential" just below "APPLICATIONS"; observe "Differential > What's cooking?" near the top of the page.
