I thought the Auto-Taxi switch had been fixed? It's working fine for me in 9.7.xb.
Anyway, the request for Auto-Runway-Ext came up last year or so. I like the idea, but as Shane pointed out, for airports with multiple-runways, it clutters things up a lot.
IIRC, I also suggested reading the winds to suggest a Runway extension. One problem with that is that a lot of airports have calm wind runways, where you land one way even up to a 10 kt tailwind.
I haven't had any more brainstorms since then. Perhaps a user option when one of the QV buttons adapts when you're within 15 miles of your Flight Plan airport, where Runway Extension moves to the top of the stack, button-wise? (Would only save one click. Three instead of four.) But "violates" my rule for consistency in the UI.
