One thing that sucks about those combos, if I remember correctly: Don’t they show only the members of the class your cursor happens to be sitting in, and not those in the whole file? That’s just monumentally dumb. I remember cursing at those as I hunted through a bunch of files for some function… only to find it was right there in the file I had up but Microsoft didn’t show it.

I remember scorning Xcode back when it was Project Builder, but saying Hey, at least its drop-down member lists work properly.
