This is the first I’ve heard of a “kill ring” thing, and it sounds wonderful. Pasting in Vim is generally a PITA because I always cut some word, then delete something to make room for it, which is itself another cut, and then I have to remember what register the thing I want is in now, and how to get at it. Double quote and then 9? I can’t even remember and I’ve been using Vim every day for a decade now.
