One thing I find myself doing a lot is going to an internet anagram server in order to generate a name or term from some other name or term, so historians and literature professors of the future can muse about whatever I was thinking when I wrote my novels. Once they are regularly assigned for all students to read, of course.
Anyway, I can easily open an anagram server in a web page, but it would be cool if Scrivener had access to that built in. This is a really low priority idea, but one of those things things that might make some people very happy.
