Well, it's good to know that it is intended to be in new releases. By current master, I take it to be from GitHub. I already cloned hundreds of megabytes from GitHub, and got lost in a morass of files. I think I will be patient, await the new FC, and probably await new firmware release.
Let me say however I am much heartened by your advice. Many thanks for your efforts. There may be others who will dip into these posts, see the good news, have more courage than me, and follow through!
