How's the registers and macro support? Did they implement base vim text objects or add in those popular surround ones? How does "." interact with macros and movement? Vim regex, js regex, something else? Do they support things like ":%g/foo/d" or ":%v/bar/d"? How about modifiers after a search like "/foo/e+2"? Does cmd+w act as a prefix for pane navigation? These are things that vim modes often get wrong and that I find myself missing when I use them.
