The trip's places went into the field's search results as they were. A place without a pin was picked as 0,0, because Number(null) is a finite 0, and a highlight left over from a longer search could point past the shorter list and throw on Enter. The phone's form, the train stations and the car stops were not offered the places at all. The places are now prepared once per form (named, with a real coordinate, each once) and handed to every location field of the manual tab, on the desktop and on the phone. The field shows them while it is empty or holds fewer than three characters, narrowed by what was typed, and derives that list rather than writing it into the search results, so a late search answer cannot replace it and a place already picked does not reopen it.
